One of these videos about snap-together joints would be great

Another video jam packed with so much great information! And as always, presented concisely with excellent examples/visuals. I can’t wait to see what's next!

Great video. I found another way to make living hinges when working with PLA. Sometimes I can position the hinge so that I can print its layers as a different color. Instead of actually changing colors, I can switch to Flexible PLA of the same or complimentary color. The layers between the two types of PLA stick really well and the hinge bends better and lasts longer than regular PLA.

While I'm not really fan of your work, I appreciate your editing. Visualising with videos while you talking is done perfectly.

Bro, you are the man. Just wanted to say thanks. I don't have any projects that require this at the moment but I'm sure I will use it some time in the future.

At 4:06 how did you print that part vertically? How where you able to print it so that it would still turn and not stick together? Or is it just print and then break the layer interface between the rotating and static part? Or is there still a small gap to give it a bit of play?

That rime you just rose to the level of bigge smalls or Dr suse yo props!! 👍🏼

I like my hinges just like my food: dead. Designing for living hinges is just much more complicated to get precise in many cases. But working with the material flexibility can make for nice and simple locking mechanisms.

would love to see a video about 3d printing threads and the different kinds of threads and how to get the tolerances to fit well even when using a not so accurate 3d printer

One thing you can do with the print in place hinges is angle everything at around 30-35 degrees. That way you get the best of both worlds with it not being as brittle as standing up, and not having that crunchiness from laying flat and having the bridges droop down. If you design the part right this way you can also eliminate the need for the moving parts to use each other as "supports" which again reduces the crunchiness.

Can you please provide a video on other common flextures that can be 3D printed besides living hinges? Those alone are awesome and great to know how to make but there's also stuff out there like crossbeams for locking pliers, and linear or angular platforms and carriages.

What the he….ck! Such an informative jam-packed video like I’ve never seen on KZfaq. Thanks!!

We're doing a living hinge mechanism that NEEDS to be vertically printed (across layer lines) and thus far we were using just a straight level with a gap, but we've now addded those toothed grooves to hopefully spread the load out and make the force to bend that mechanism uniform across various user printers

I just gotta say, your videos are the best modeling course out there! I just saw your other video about printing boxes diagonally and that made me think, would it ve possible to print a box diagonally if it has a print in place hinge? That would maybe fix the issue you described when printing it flat on the build plate "rotation due to saging" and would be a little stronger than printing it vertically. What do you think?

I love videos like this

I would love to see a video from you on Linkage sets/mechanisms

I couldn't stop watching your spinning AHNold head. You said something about hinges? 😁 Good video. Thanks!

Great little tutorial! (Any chance you can get rid of that spinning head behind you? It's really distracting! ;-))

great intro. I love wordplay

Could you do a video on clamps?

I like your idea of a hinge that rotates around a "hinge pin"" and is essentially 3 D printed as one piece - if I understood you right. I would like to incorporate that hinge design into something else. Are there instructions on how to create those "bolt like" mechanisms that rotate around the hinge pin?

Came from hackaday! Great video, some fantastic information here

You doing so well👍🏻

I'd love to see you cover sacrificial bridging layers in more depth.

When I print a two-layer strap from a bottom layer, the two layers kinda detatch and turns into a nice living hinge when I fold it. Living hinges don't just have one printing direction.

You should resell that as a small vice for straightening the pins on through hole chips. The circular hinge

Can you make a special about axle and how to design it?

Nice!

I've found that if you make the horizontal hinge as stubs instead of a shaft it prints quite well and can be very strong.

It eould be great if you acruay discussed how to make the livinf hinge in the vad software.

Polypropylene, if you can get past the printing challenges, makes for amazing living hinges due to its high material compliance

Have you done anything on compliant mechanisms?

Kind of makes me wonder what the functional range of each of these is 🤔

At the end of this video a now we part ways pun was missing... 😂 I smoothed out the rotation action on a horizontal printed 'grown' hinge using a drill and an adjustable clamp to hold the center (safely away from hand). A little lubricant in the form of alcohol (dripped in and let the capillary action carry into the piece void) and some careful application of rpms. A little heat friction goes a long way. YMMV. And you have to work out how to attach it to your drill. I used a socket and and some museum wax/puddy clay in this one case. You don't need much. My hinge wast hex shaped. Tape would have been enough tbh. If it starts to smoke you've gone too far/fast/long. 😅 Again ymmv.

What about hinges that need to lock in position at a given angle? Like to provide an adjustable viewing angle for an lcd screen holder for example.

What program is being used to do this

Hi.. quick question: Can you please let me know the software you are using for designing the parts?

i'm trying to design character joins, any tips

Why, why are you creating stress points in otherwise great hinges?? You start with a hinge with one stress point. Solely by making it of equal thickness you can achieve much better longevity. Ok, you got great idea and made a circular hinge. Why would you introduce a lot of stress points into it by those grooves?!

A really well-explained video. However, the spinning head in the background, coupled with the rapid-fire explanation, wore me out. This old codger needs a bit more time to absorb all of the talents demonstrated.

What about bolts and nuts.

Would like a video on rivets or pop-fasteners, self locking fasteners - shafts - hobs instead of bolts and nuts.
