Kinematics is a system for 3D printing that creates complex, foldable forms composed of articulated modules. Use our free app to design your own flexible bracelets

I've uploaded a selection of different bracelets in a few different sizes. The sizes indicated on the file are the size of your wrist for a proper fit. If you need a different size or different style, just go to the app and design one to your liking.


3D print it

We suggest a layer height of .2mm

You should make this into a tie!

good job nice system. we need to write our congress and tell them to get these printers in the class room at grade level instead of fn i pads

I'm using a makerbot gen 5 with 'standard' settings (infill: 10%, shells: 2, layer height: .2mm).
After printing, its difficult to break free the joints without destroying a few hinges. Any advice?

Thanks for this, very interesting system!

Love this! A faster/better version of what I've been doing, which requires hand assembly (not fun!).

I made a Time-Lapse video of this print. Check it out at https://www.youtube.com/watch?v=Yqe-6fYT-EQ

Thanks for the model (and the app to build it). On the fifth picture the closing mechanism looks different than the one from the objects created with the app. Is there a way to select it too? (I presume small magnets).

Cool, thanks a lot for the design.

Printing flawlessly on my flash forge. 20% infill PLA.

around 50% done. hope it can end well =)

Just beautiful design! Printed at 0.1mm 70mm/s and 80mm/s infill with my UM2 perfectly !
But anyone had problem with the "pin" ?, it's just impossible to attach, so beautiful but unusable :(

Hey, great design -- thanks! PLA printed successfully first try (Netfabb cloud repair + Kisslicer) with the exception of the clasp stem which deforms a bit due to its tiny diameter. How about a version with an easier to print, more secure clasp, something like this: http://www.thingiverse.com/thing:198335/#fileshttp://www.thingiverse.com/thi... ?

Buckle strong, easy printable supportless

I have printed on my aluminatus, 0.5 nozzle 0.4 layers, and it was pretty close to staying together, I think Z start position is fairly critical on these large layer heights, will try on thinner layers

These are really cool but has anybody been able to print them on Ultimaker2? I just got a big pile of puzzle-pieces as the connectors are too small and the pieces doesn't stick together.

Just uploaded one made with ultimaker original. Works like a charm, just print it slow round 30-40mm/s speed.

Hi Peter, most people who have been printing so far were using makerbots. This guy did use an ultimaker though: https://twitter.com/jeromemaurey/status/405804964871962624https://twitter.com/jeromemaur...

We are planning to make the joint tolerances adjustable as well. I'll let you know when that modification is available.

Great! I will do some more tests as well.
