Should have charged 95 dollars for it lol

The stl is available ….For the tens of thousands of people who need it 😂. Nice vid though 👍🏻

I’ve worked for a company that made car parts, and they were practically incapable of making a single piece of anything Even the prototype runs of a new part went in sets of 5 One time someone ordered a replacement part for a car, we had to make 20 parts because that is what the production run was tooled to do So that means receive the order, locate the old tooling, run all of the pieces for the 20 parts, paint them, assemble all of them, packaging the parts for shipping, and shipping them using FEDEX rather than putting them in a regular freight truck It took all day and was handled by over 15 employees over the course of the process… Then it gets to the company that you ordered the part from, they sell you the ONE that you ordered And… Do what with the other 19? Store them in the hopes that someone else needs it? Having to count it in tax inventories every year they don’t sell? Just scrap them?

@@drthmik That makes the 95 dollars look like quite a bargain

You need to send an email to them and invoice them for $100, plus an hourly rate, plus a broken 3d printer file example, and then send the link to the correct online file.

He didn't take into account the cost of his 3D printer, Fusion360, and other tools he had available in his workshop. For a collector who doesn't have those lying around $95 seems a fairer cost. For people who does though, yeah $0.09 is definitely more appealing xD

@@ZenoAmbrosius well in the other video he used for reference the part also looked like plastic, also i would doubt that the wear on the piece is actually so much a good 3d printed part would not handle, not 9 cents but i would bet money that if you refine just a little more you can get the same result for something under 10 bucks, hell if don't have the printer you could just order the service online just giving the piece specifications, i'm not saying that the original company is not a good company but i am saying they at least could had told him "oh you are missing a gear that interacts with the mechanism right there" but they didn't, they offered a whole new mechanism to substitute a minor part so yeah not the best

@@jellyfishwiggle8721 And youre not taking into account that fact that there's 3d printers everywhere around you. Here in Toronto the libraries have them. That means you could 3d print the repairs locally on a 3d printer for much less than $100. Its free to use 3d printers in our free libraries.

Thanks for the feedback!

yeah, 3d printing a part for an obsolete paper stamper is a totally relevant and practical use case...

i was thinking the same thing, sitting here going " 36, its 36.... 36 damn it"

Nothing wrong with figuring things out empirically -- if it works, it works. There is no right way despite what the education system brainwashes you into thinking.

@@tinkeringengr the education system only "brainwashes" the ones who are not very smart or creative to start with.

I agree, if you're going to source new-old parts for vintage machines don't expect it to be cheap. It's like if i go to Holden (dont exist anymore) asking for a new-old stock part for a HK (1968 car) and then being shocked at the price of the part? It would amaze me if anyone had a massive stock of new old parts for those cars.

@MeandMyStaffy Because it's a vintage part that isnt produced anymore?... The rarity and time of holding the item makes it's price go up. You've obviously never bought any vintage sought after items before.

@MeandMyStaffy If it is a machine they do not make anymore then they also do not make parts anymore as well which means the only parts available will be those left over spare parts that were not ordered before people quit using it. That means they have kept those leftover parts somewhere taking up space that could be used for parts they sell a lot more of and maintained the record of their location for decades after people stopped buying the parts. The company has the expense of keeping parts and maintain records for decades just on the chance that somebody somewhere would have an old machine that they wanted to make work again. Then there is the fact that the rarer something is the more it is going to be worth. That is why gold is a lot more expensive that copper and copper is more expensive than aluminum.

Yeah, it kinda made me mad that he acted like the company was in the wrong for wanting to be paid for storing parts decades after they became commercially useful. Like, "My god! My hobby is expensive? HOW DARE YOU!"

Honestly it should be a requirement for schematics and parts to be made available for everything being made. #RightToRepair

Yeah, 50 years is some impressive long term support

I wonder if they make refrigerators, stoves, ovens, washers, and dryers too. I would gladly buy my household appliances from them. I'm tired of seeing major appliances breaking down after just a few years when they used to be built to last. Time clocks are found in offices, but so are refrigerators and microwaves.

chances are it's not a wholly uncommon piece? might be a touch hard to acquire but i reckon it's 95 bucks because it'd be casted plastic rather than 3d-print

@@mcfixer9503 95bucks was the price for the complete ink cartridge assembly including the metal frame and the missing gear. and prices for these types of replacement parts that are not the typical wear parts are highly comprised of the additional cost for storage, handling, service, and shipping as these parts of the company are usually not making a lot of money providing massive amounts of replacement parts... pricing is fair for something that is ordered every now and then and 95 is not to make a profit and just to keep this service afloat.

Because most people won't put PLASTIC in something that really needs to function. Imagine you need a surgery and someone 3d printed a piece of your bone

A coworker designs and prints wheel chairs for disabled animals.

@@algoriithmtheproducer They do that... They literally 3d print surgical materials all the time.

The problem is that a lot of people don’t know how to design stuff so they end up printing cell phone holders. I’ve used my 3D printer more for work (industrial automation) than for random stuff.

It's because mainstream 3D printing isn't done by 3D CAD Modellers, it's done by hobbyists and companies / people trying to make money of cheap toys. The practical use cases for 3D printing can really only be understood by the people that are familiar with the 3D printing technology and how to utilise it to the best of its abilities.

$95 is a "why are you still using a 50 year old time clock?" Price and enough to make it worth it to then if you really want it

Yep, not to mention the cost of the 3D printer and software.

Well it depends on how much you value your time. Print time was 27m as shown at 11:26, let's say 25m to engineer it, (think of what to make, measure, model). 2x print makes it 79m or just under 1h30m. At 15$/h that's 22.5$, 30$ at 20$/h. Not sure whether printing time should be counted or not, but that still ends up being under 95$ for the full assembly, of which just the gear is needed.

So damn passive aggressive

@@rose1770 Depends on the business and stuff, but I know first hand how much things will sell for. I mean: if something costs $30 to make, it often sells for $60 or $90. Also keep in mind that the original would probably be made of metal, increasing the cost to manufacture. So $95 may be reasonable for a company that needs to pay more than a single production engineer, but it obviously isn't for someone with a 3D printer.

Good tip!

Could you also have repeated the feature, i.e. the cut rather than repeat on the sketch and select all the faces you want to extrude?

@@manyshadesofbrown yep. That's also An option. Probably the easier one :)

Alternatively, you can specify the tooth count as floor(360/tooth_angle) Algebra!

@@OllieVK And the cost of the first test piece = 18 cents.

@@andyu69 and cost of youtube an the charge of the person who put the tutorial on youtube..

The printer, the knowledge of how to use it, fusion and the knowledge of how to use it. The time taken to produce it's several iterations.

Well it cost about over $1000 to print that part.. its a prusa 3d printer which is at least $800 and thats a kit, so you had to make the printer 1st thats at least a few days, then learn fusion which takes around 1 month (it took me a month to learn the basics). Now with all that done you can now print loads of different stuff but you couldnt do any of that without the printer, so a normal company isnt going to do that to save $90 and that $90 is tax detuctable from your companies funds so buying the part is the easiest way and the most cost effective way, it also helps the company who makes the parts employ people.. so doing this you have or could have made a company made some of there employees reduntant 🤔🤔 3d printing is great. Personally i would of made it out of nylon carbon not pla. 😂 so its not a $9 part is it now.. 😂 knit picking yes but thats why we all love the internet ...

Thank you so much! Agreed, I love old tech.

A lot of new tech comes with parts of the user agreement forbidding "tampering". They want to keep you buying new products. Planned obsolescence.

The lack of screws in modern tech is even worse, you cant open anything up without prying open fragile clips anymore.

And the laws as well. All this subscription rather than owning, enforced by the companies, and the "you aren't allowed to repair it" bull

plus they will void your warranty if you attempt repair yourself.

there's many many tutorials on youtube that'll teach you different 3DCAD softwares. This design was really simple and If you took just a bit of time to understand the program through youtube, you'd be able to make it in less than 5 mins too( I taught a lot of friends how to use solidworks, it's basically just a bunch of sketching using lines and extruding/revolving)

I love the idea of being able to create replacement parts & products at home in a 3D printer! However I do question the sincerity of this video’s title. The part costs $100 on the open Market! In order for you to create this part on your own, you’ll need a few things. From what I’ve seen, a decent entry level non commercial 3D printer is going to run approx $750 and up! Then comes the real hidden costs which you pay in sweat equity ie. acquiring the knowledge & skill it takes to produce a clean functioning part! At some point, I believe 3D printers will be a fairly common & simple to use house hold item. Maybe never quite like a Star Trek Replicator 😢 but simple & intuitive search engine for 3D models & simple & intuitive printing hardware & software! Not quite there yet. Meanwhile, for most of us dummies, ordering the part online for a hundred dollars is the better way to go. (Update)- I have had enough people reply to me that I am wrong about the price of good 3D printer. I got my information from the internet about 6 months ago! Apparently prices have gone down drastically since I looked into it, or the info I read was wrong to start with. One guy is telling me he uses his printer “every day” & only spent $170! 🤔 Anyway ok! I got it!!

@@dwmueller76 Although I agree with you , I believe that you are a bit misinformed. You can absolutely buy a good 3D printer for under 750 dollars. My printer, an Ender 3, was less than 200, and it's been great. My friend just bought one and has pretty much been printing straight out of the box, and he is producing good and funcuntioning prints. Ofc you can dive deeper and create better quality but that isn't necessarily needed, not even for this part. It's also not like you would be buying a new 3D printer every time you want to make a part to repair something. Also the idea of just searching for models and printing them has been around for years in the form of thingiverse and other websites. I have the knowledge to do CAD, but it isn't necessary to be able to do so in order to print what you want. Now ofc in order to print something as specific as what he did in the video, you do have to have that knowledge, but most of us have far more modern things. There a parts online that fix problems with my car, for example. I definitely do agree that his part cost more than 9 cents, considering even just the basic labor time. But, you also shouldn't discount the ease of fixing expensive things with 3D printed parts, because it's still much easier than your comment makes it out to be.

they could have just sent the gear for a lot cheaper

@@dccatsnatcher2411 Yeah but you know it's a vintage clock. You need to keep the parts in stock for the old model. And keep the guys on the payroll who know how to fix it.

@@dccatsnatcher2411 i dont like the pricing either but because of its context i can understand it too. Its the same with antique car, gun and other machinery parts

@@kwinzman Exactly. Even offering replacement parts for these machines instead of attempting an upsell to something newer is pretty darn impressive.

Thanks for watching!

Yeah, but I bet they don't sell many spare parts for this thing these days, so even the stamped metal piece probably has a huge mark up on it. Even if you were able to just buy the cog they would have to charge way more than you could 3D print it for, simply because they have to cover the cost of storing them and paying full time staff to ship them out on the rare occasions people order them. Also, it cost a few cents, but that's only in 3D printer material, it doesn't take into account the other costs involved in making this 3D printed part or the hours of energy spent on making it. Like how much is your time worth, what's your hourly rate? How much time do you need to spend learning how to use the software and getting your 3D printer set up? How much did the printer cost? How much did you spend on electrical energy? How much energy did you use just learning and printing test pieces before you can print that one piece? If we're more honest about this process, if your only aim was to make this one cog, you would have spent way more than $95 to 3D print it. Just buying a 3D printer and getting it set up would cost you more than $95.

imagine if he billed his time out including the assembly and printing as well as the design of the component 2 prints = 50 minutes and then at least 2 hours for the rest of the time , 35 per hour means it cost more to make 1 part, that justification is not sustainable unless you are printing thousands and selling them for 20-30cents minus tax and the cost of electricity...

@@silentassailant3905 and @Red Cube yeah these are all good and valid points I very much agree. I think this was just the appeal point angle he was taking for the whole video so he had to big it up a little. Also I think the lack of people to adequately calculate the total cost of things from all inputs is a fundamental human condition. It's what facilitates companies like uber running their drivers into the ground, as the fares barely cover car maintenance for wear based on miles drover just for uber, let alone a salary. It's also a key point of all this sustainable development goals stuff that's going into high gear, they are going to try and expose the hidden social and environmental "costs" of things, of course it won't be done in a fair or reasonable manner, and just result in exploitative practices and rent seeking, but who knows I hope they change their ways and prove me wrong....

I was about to say the same. Is great to ve able to repair something by ourselves "just" 3d printing it for "cheap" .

Honestly it's surprising to see that the company even bothered to support this request. This time clock is ancient at this point. The fact that they are still supporting it and allowing users to buy parts is definitely worth the $95. Like I get that the company probably paid nowhere near that but still that level of support for a product is insane. I work with enterprise OEMs all day if I asked any of them for a part on a model that was over say 3 years out of production (and not a part shared by in production models) they would look at me like I was insane for asking.

So satisfying!

Of course. This is ancient tech and im surprised they still offer the part. To play the devils advocate, lets say this took 1 hour to model and print (including revisions). Factoring that in, the price isnt so insane. Only business owners would be buying these kinds of parts.

That price also included the metal bracket assembly. We were not told the price of just the gear, if available separate.

@@wilk7255 Exactly my thought!!! It **is** a tad unreasonable for them to not provide schematics of the gear tho.

How much money should the company spend to warehouse old parts for products they don't sell anymore? They aren't making one-off gears, they had a mold or shop make these by the hundreds. Today, they need to charge enough pay salaries, and keep the stuff around. It's not free, and you can't salary people with a trickle of odd jobs.

That’s awesome to hear, thanks for watching!

Or, in the quantity of the pattern use 360/Teethangle. Making use of the already created parameters

These are both good solutions. The first being better for trying multiple tooth angles/quantities, the second being better for quickly being done with the teeth as a one-time process.

That only works if you know that a circle is 360° though XD

learned this in my mechanical engineering technology course. Very Useful!

or made the outer diameter bigger with d(xy)+1 mm and the mm filling lines to construction lines, so you can select the 1 mm bigger full circle to cut out.

It is not simple. It is intuitive. I do not see any other creature on this earth able to make such a tool to fix it, but the way a supercomputer, to a computer, then to a printer and coming out with a product is amazing. Old times, a person would carve out a wood piece or clay, then make it into a metal piece by melting steel into it, the planning to make a piece like this on paper and ink, math. Gear ratios, size parameters,Vision to make all the parts work together. It is not simple.

How much do they usually cost. Sorry , google sometimes doesnt give accurate market price

@@CS-et4fs you can get a small one for 200-300, but that's much smaller than filament printers for that price and prices go up fast for the larger printers. You also need a bit of a hazmat setup to handle liquid resin.

@@patrickkeller2193 "hazmat" is a bit extreme, but you definitely need to take ample safety precautions and make preparations for using a resin printer. It's a 3 step process, in the first 2 steps you need to use and wear nitrile gloves so as to not handle the toxic materials (resin is toxic, and 99% IPA isn't toxic but it will dry out your skin and is necessary for cleaning your prints of leftover liquid resin) The third step is to either leave the print out in sunlight or to place it in a UV light box to cure. Just a pair of nitrile gloves and a gas mask (Isopropyl likes to make fumes) is basically enough for handling the materials. It's suggested to get airtight sealable containers for your IPA and to keep your whole setup in a place that has good ventilation. It's definitely a LOT more work than filament, but the final products you get are still super sweet!

save $100 by spending $800

Lots of things like this are only available as sub-assemblies, perhaps because the company selling the device subcontracted the part to another company, who only sold them the sub-assembly, not the gear. I hit a situation like that recently with my older minivan with power hatch. The motor drive was fine, as was the arm that went from it to the hatch itself. The ball and socket piece at one end of the arm broke. The assembly could only be purchased together; hard to find, costing a few hundred dollars or so. I was finally able to find just the end piece and attached bolt at a salvage yard for maybe $10 cash, they charged less than normal because they let me take it off the old vehicle myself.

Even if they did buy the cog as a separate component in the first instance, they would have assembled all the sub assemblies at one time, and then shelved the parts for use as spares.

@@almostanengineer More than likely, since their field service techs would replace the entire sub-assembly.

It is (accidentally) good practice to include an odd number of teeth for a part that goes through continuous wear. Unless the step size for each punch operation is 5/7 teeth, That way you do not land of the same teeth every time. The real missed opportunity here was to not use 37 teeth which would've been a prime number (and so close to 36).

@@ShreyasBharadwaj See, What you don't know, Is that I know this already. Prime numbers mean no factors which means no repetitive loads on specific teeth, However, This is interfacing with just a single bar, And if it was made PERFECTLY, It wouldn't matter, As the perfect gear would only advance one tooth per pull. However, That would require measurements on the travel distance of the bar, Which wouldn't be THAT hard, But it would be more difficult.

a rule of thumb just for fdm 3d printing an existing design (i.e. take a file and get a product.) is to take the filament cost and multiply it by 10.

Importantly though, the value of your time only counts if you're doing something you don't want to do anyway. If a movie ticket costs $5, you don't say "well I'm also giving up 2 hours of my time, so actually it costs $5 plus 2 hours of salary". Because the movie is what you want to spend your time on.

Nice! In my own experience, parameters are really useful when you have a dimension that you might want to change, and as a way to keep track of measured dimensions.

Using the parameters helps you with how you analyze the problem, it gets you to think of the details and how they interact with each other, so you can identify them more readily in the future. Basically improving your technique through experience.

Thank you so much!

I’m so glad to hear! Thanks for watching 😊

@@MorleyKert I am more a Lightwave man myself.. But that was designed to be a half good at D3 animations creations, half good at CAD.. But the fact that you have render by parameters functions... This has made me very interested.. I've not seen that in Lightwave.. (though it may exist, but I certainly don't know about it) I may have to have a play with Fusion.. See if I come to like it.

Not really, because wouldn't it still depend on the tooth depth

@@sir_john_hammond no

I came here to say the same thing. You can see the tiny gap between each tooth. But I guess engineering is about 3/5ths approximation.

Exactly, the manufactured part will last for decades with millions of turns.

That makes sense! I do believe your point is valid. Quality over quantity. The manufacturer is always going to have much more overhead cost to create that part compared to what Kert is doing whether it's plastic or metal. The example piece that was taken from the three second video looked like it was plastic although it was from a different model/manufacturer time clock. At the cost the manufacturer quoted Kert, he could make 1,055 and half of these parts via his .svg file he created and in less than 20 minutes for each part. The biggest variable is use! How many times is Kert going to punch that time clock before it breaks? I'd like to imagine Kert punches his time clock every day.

Thank you!

Yup I definitely did not think through this step haha

Also would have saved time to do the extruded cut for a single tooth and then do a circular pattern around your axis for the rest of the teeth instead of selecting every instance of the tooth to cut. But it's easy to have these ideas when I'm just sitting here watching on my phone :)

Thank you so much, and thanks for the tip!

😂🤣 Competent designers make things standard 🤭, sorry but usually parts are made awkward so you need to go back to the manufacturer to get replacement bits, I'm a designer who tries to use standard diameters and materials but am also a toolmaker who has to repair tools or parts for other people and nothing is standard which is so frustrating when you can see its been done on purpose.

@@ricardo-iw9sq I was always taught to use standard sizes when possible, and as a machinist as well, when parts come by. More often then not values are at a standard sizing on a print. You don’t make things precise if they don’t need to be. Or at weird values. If not you need custom tooling of weird dimensions. If a hole needs to be reamed. Why buy a custom reamer that is pricey, when you can buy one of the standard sized ones for a fraction of the price since they are made by the millions. Obviously sometimes you can’t help it. But say those holes in the stamped sheet metal. Those are made on a press and I can almost guarantee you that they used a standard sized punch to make it because they are cheaper. So therefore the part going in the hole should be close to standard as well. Sometimes an intern won’t be thinking like this when making a part but generally speaking competent designers will know where they can save their company money by using common tooling.

@@knightfall7534 Hi, I totally agree with making things standard but i used to have to repair press tools and the seal sizes on the tool were not even close to a standard either uk or European so we had to get them made special and i did finally convince the customer to alter the tooling and piston groove sizes so they would be an off the shelf item, I have also done bits for cars and they a renowned for being assholes for stupid sizes. When I have a drawing sent to me I will quite often call up the customer and say will a 25mm dia bar work or do you want 24.5mmX 1m and then they say no 25mm is ok its in fresh air, I then say can you ask the designer to look at material sizes other wise its going to cost them, and 9 times out of 10 its a graduate thats never designed and built something from scratch. Happy days 🤭

@@ricardo-iw9sq oh for sure, some people who don’t know the practical side of machining won’t understand why dimensions need to be certain sizes. Engineers who never touched a machine of their life are known for this kind of garbage. But like you said usually they give in and realize it’s better to go with standard sizing at the expense of cash.

thank you!

Yes!!

I have a microsd card holder off ebay that is 3d printed and it is a brilliant little container. works a treat and way better than the crap from china.

Exactly my thoughts

Thank you so much!

It depends on what you're designing really, if it's a simple thing and you know what it'll look like from the start, or if you have a complex assembly with a few key parameters that drive a lot of features across a number of parts then it can save a lot of time. For general design, however, it's just a matter of preference. Personally I think I've bothered to set up global parameters only a handful of times in my career, and of those times I certainly recall times where I've tried to be clever with parameters and it actually causing more trouble than it was worth.

Also, how much were the practical elements to make this 9 cent piece in the first place? 3D printer, computer, software, electricity etc. When you buy a product it's not double the raw product value, allowing for profit, you have to factor in so many other aspects.

Fully agree here, the "it costed me 9 cents instead of 100 dollars" thing is blown out of proportion, since, as pointed out by other comments, it was not the gear what costed 100 dollars, but the whole working piece. For a proper comparison, the piece that was currently in the machine should be valued and included in the cost of the end product.

This time clock is a functional display piece......its not meant to be used everyday.

It’s cheap enough to make 1000 of them for the same price, so I think that’s a fair trade off.

You can make things tougher by printing in nylon. Someone replaced a high-speed part of a "Magic Bullet" blender with a 3d-printed nylon part, and it held up fine (though PLA pretty much disintegrated in a minute or two).. Though it will wear out quicker than metal (by a lot), even the PLA will hold up well enough that it shouldn't need to be replaced that often (at which point, just print off another with no design work for like 9 cents)

This function will put very little wear on the teeth. Indeed, the teeth rub against a smooth piece of metal. I think the little knob/bearing on the bottom will get by far the most wear.

Then you print another one

Thanks for watching!

@@Eyes0penNoFear exactly. thank you for distilling the bullet point I was trying to make.

you think the company has to reverse engineer every dimension of the replacement piece? they have a bucket of them somewhere from the last time they pressed play on the injection molding machine they had spitting them out at 20 bucks a 5k piece batch. im not saying they should sell them for 9 cents, but they definitely shouldnt be selling them for more than 2 bucks

@@XcaptainXobliviousX you don't understand business. I'm selling $1 chinese cards $150 a piece. Customers don't need to buy from me if they have a laser, but they don't.

My thoughts exactly. $0.10 and $1,000+ and hundreds of hours.

​@@XcaptainXobliviousX 50 year old specialized parts are going to be sold at a premium because generally it is not profitable to sell them otherwise.

Thank you!

Thank you! You’re totally right

Nice call. Patterns are extremely powerful in Fusion 360. To do it without a pattern I would have started with a circle larger than the gear size and turned the "ShadowDiameter" into a guide and then one click would have selected all the gear to be cut. So many ways!

Furthermore, the number of teeth could be calculated by putting a formula into the circular pattern. The formula could be something like 360°/{teeth angle}

Thanks for watching!

Even if the part wears out over time, a new one could be printed for little effort. Could also use the print to create a mould for a more substantial material. Maybe even dabbling in some backyard metalwork.

this is a very very low-wear application. The axle is probably more subject to wear than the teeth.

Thanks Jeremy! Parameters are absolutely incredible for designing functional parts that interact with existing stuff.

@BuildGUY can you explain what you mean? I’m just getting into this. One of the other examples I’ve seen cited often is like if you designed a book case you could change the number of shelves or the thickness of the material, etc. That made sense to me, perhaps a little unnecessary, but it seems like a simple case of it being useful, so I’m just wondering if you have an example where it’s either doesn’t work or is maybe not worth the effort or something.

Still a win from my end!

@@MorleyKert Exactly! You could in fact buy a similar model printer new - they sell (or sold recently) similar ones at Staples but whats the fun in that? LOL

Thank you! I think the gear will last a long while, because the original gear was also made of plastic. If it breaks, I can always print another!

@@MorleyKert There are of course different types of plastics twith different wear levels.

I've been using fusion for a couple of weeks now, moving from solidworks. I should've made the move much sooner!

@@imqqmi why are you moving from SolidWorks to Fusion, and why should you have done it much sooner? I'm just learning SW

@@keithwins Through work I had access to SW 2017 with hsmworks, it was buggy and tedious to work with using cam. Fusion 360 is better integrated and feels a lot faster to work with (still using my old pc from 2014, 3.1ghz quad core 16GB though). After upgrading to windows 10 I no longer had access to a working sw and hsmworks combi, which is fine for 3d printing but not for machining aluminium. I really wanted to use hsmworks adaptive clearing. I've exported drawings in dxf and used them as 2.5d cam in vectrix, not ideal. Fusion just has everything I need and is free for hobbyists like me. With my sw and hsmworks knowledge I was able to design a simple touch plate and output compatible cam in fusion 360 within 4 hours. I was amazed how quickly I could pick it up, after weeks and weeks of sw learning and some weeks more with hsmworks. Granted, that prior knowledge greatly sped up what to look for in fusion 360, but it's just better integrated. And it doesn't crash so far and doesn't complain about low resources as sw does. Ok so I loose some features that only paid tor users can access but I can work around them like the rapid moves are the same as g1 moves, 10 active read/write documents limit etc.

Thanks for watching!

Yes that’s the kind of things you learn when you run a company or you show interest on how companies work. Thank you for this comments as it’s highly more interesting and true than the usual too simple sentence « company always want to scam you »

Very good points. Try looking for replacement parts for an old appliance. The price seems very high, but the parts had to be manufactured, inventoried and stored for many years. This is why 3D printed parts on demand will grow, you could purchase a part and have it printed then shipped, or even better purchase the design and print it yourself. I found that another advantage is the time savings and shipping costs of making your own part.

That gear should have some other thing on the backside to prevent incidental removal with the cartridge. C-clip, E-clip, cotter pin - just a few possible devices, one of which should have been designed into his replacement part to avoid the incidental removal of the gear with the used cartridge.

When the device was in use the company might have offered parts of the assembly separately but considering it has been out of date so long it isn't unreasonable to only offer the full assembly now.

If it's really a concern you can do a metal part with lost pla casting.

Which is why when products like this age out, it should be open sourced.

Thanks! The gear that comes from the manufacturer is plastic.
