Chain and Pinions

Just a test to see how would it work a printed chain drive system.

It works but... because of the "curling" of the filament and the inaccurate assembly of the steps, the chain is too much tensioned to make it move with a nema17 like motor.

Thus the results of the test are: needs improvement :-P

Sorry for:
1. The scad file, it works fine for the assembly in the pictures but it has not been tested so it may not work when you change the parameters.
2. The instructions... too much words I guess...

*** UPDATE ***

There's people out there making things with this thing, GREAT!
So I've make few changes to the code to make it a little bit easier, just a little bit.

Basically, now is easier to stack pinions together.

I remove the scad file and upload the new version (which is also capable to produce the old parts), I also upload a screenshot from one possible set of pinions and, of course the stl files for this
