This is one of the coolest, most practical things I've seen done with a 3D printer :o

Thanks for that. The idea started as a way to make a turbine on my printer, the potential usefulness came later!

This is an incredibly good idea! Considering the cost of buying the rotary tool alone makes it worth it, but even moreso considering that this one will keep a workshop much, much cleaner, and the vac can be used on its own! Great job, and I look forward to the progress!

I'm new to Dremels, but this thing has been great. kzfaq.infoUgkxfPgcZ5_Cl0HDUKkMJAKde11YKQZVgMoR The variable speed is awesome and the cordless aspect makes it so easy to work with. I am constantly finding uses for it that make tasks easier. Recently I put in a new deadbolt on one of our doors. I knew I had to enlarge the hold where the deadbolt goes into the door frame. At first I thought I would have to get a big router and figure out how to use it for that, but then I rermembered we have the dremel. I was able to enlarge the hole almost as easy as if I was drawing with a pen. It's also great for grinding our dog's nails done and so many other household tasks.

When I first ran it I thought the same. I was reading QF 32 at the time (great book) and was aware of the dangers of exploding turbines. Actually, the PLA I used seems to hold together OK, so a production version with metal or injection moulded plastic rotors should be fine. The bearings are a challenge, partly because the 60,000 rpm is too fast, and because the plastic cannot conduct the heat away. Laser cut metal rotors would help, and the front bearing needs a good shield for dust protection.

I would buy one. The choice is yours.

Awesome!! That would be even better if you could put a flywheel in there to give it a bit of momentum...

I really like the concept and i will definitely be making one of these, when i get my printer! It will allow me to "dirty" stuff in an office space (my appartment). :D I think of making a velocity stack on it though, so it will suck dust from a larger area, but still have high velocity at the fans.

That is some crazy rotary tool !!! brilliant.

Very clever idea. I like the fact that you bring the heatsource from the normal moter away from the hand. It is only a plus that it also takes the dust. Great work. If it is possible i would like a sample for my workshop.

I machined the main shaft on a lathe, it is not a standard item. The nut and collet are Dremel, the bearings common industrial, and the plastic parts were 3-d printed.

This is just amazing, I am thinking of the applications this could be put to. Maybe a complete workshop run on a few vacuum cleaners

I am Seriously Impressed. I read your statement on Thingiverse. Designing a Product? You game at least 7 just from watching the video. I definitely got some work ahead of me.

Wow, I had no idea that orange 3D printed turbine could do 60k rpm without flying to bits. Great idea.

This would be a Godsend for bone cavers. Bone dust can make one very sick, and high torque/high vibration devices can create microscopic cracks in the piece that can comprise its structure (ie; falls into 2 pieces when you are polishing it). This could save a bone carvers lungs/life.

COOL. looks like a nice addition for my tool box. i will defiantly be making one. my girlfriend works at a veterinarian and they use a dremel to do dogs nails, this seems like a much better option for light work like that.

I hope you patented it. This was genius!

You have to get a patent on this tool its so Nice

Very cool, I would buy that.

Well done,very useful tool and well made too!

Genius!! I absolutely need one if these at my shop/garage lol! I know what my next project will be

Seems to have more power than a Dremel 3000. Very nice work! Thank you for share!

Thanks for your comments, but I only made one for myself, and have no plans for commercial production.

fantastic! i'm so willing to try this myself since I got a solidoodle this month.

Awesome, will try that one as first thing when I get a 3D printer!

All I see is little metal bits flying directly into the bearings, making this thing a spinning explosion of plastic parts when those bearings finally fail. I know it is awesome, but I just can't help seeing it like that.

where can i get the shaft?

A production version should have rotors made of thin laser-cut steel which are twisted into shape, so the whole shaft would keep cool.

It will be quieter if each disc has a different number of blades. Like 14 13 12 11 instead of 12 12 12 12. What you made is basically a siren.

Very impressive. Don't the plastic turbine parts get deteriorated by the metal dust?

! that's neat

I have not tested it much, scared of the PLA which softens easily with heat. Composite cutting with the discs worked better than my Dremel, with the higher speed, and if the disc jams, the lower inertia and stall torque saves the disc where the Dremel smashes it. The little grinder worked about the same. Proper torque testing and rotor optimisation would be good.

you could probably design a smaller one that can fit inside the vaccume tube and has an outer cap to keep it from getting sucked into the vac. that way worst case scenario if it does burst its inside the vaccume tube (you can buy shop vac tubes that are steel i believe) and it won't explode all over you. (though all of the parts are now inside the vaccume)

@Richard Macfarlane Yep rpm is awesome but torque must be very low. A cutting speed caparison whit that dremel wold be great.

Oh, so you fabbed the metal parts as well? If so, would you be so kind as to list or make available the specs of the metal parts as well? Would be greatly appreciate if you could.

This is a 1000Watt grinder!

Fanyastic.

can you use the shaft and bearings from a Dremel flexible shaft kit?

Can we use it on a low end cnc to cut wood? Or a corded drill is better?

wow my dremel broke and i see this and i have a small and more portable shop vac i thank you sir

That could be used as a spindle for milling..! :D

Nice dude! Try making one with the ball bearing from a garret turbo or the ceramic ones from turbonetics, those spin up to 100k

That's epic, well done , I'll be printing one and doing some experimenting. Wouldn't using less suction cause it to spin slower ? 60k is a bit brutal lol

Wow! This is extremely clever! Would you consider selling the metal parts?

What is the metal part from?

Yes, this would be a good Kickstarter project, but not for me as I only did this for fun. Somebody else can make it happen if they want!

It's thing 76369 on thingiverse. (youtube won't let me post links)

Nice! is it on thingiverse?

But doesn't to vacuum pull way more current than a normal brushed rotary tool

hi i am really interested in this turbine rotary tool i have already downloaded it and will be printing it soon but i just want to know that where could i get the bearings and the rotor shaft and other parts so that it could be a functional and complete device thanks allot mate and please could you send me a reply

highly energy inefficient, other than that it's a neat toy.

where i can bay it?

kickstarter please!

how do i made one for me?

anyone know whaere i can get that shaft?

Kickstart this. I hate nothing more than the debris that comes from using the rotary bit.

where do i buy those spacers and shaft, anyone?

Kickstart this, plz, and TAKE MY MONEY!!!

Funny that Dremel took this idea and seem to have made it crap with the dremel vrt1-1/5 which looks totally gutless compared to yours.

rip my ears
