Summary

A NEMA17 version of J_T_3_D's rock tumbler.

I used a cork gasket/damper for the NEMA17 and glued rubber feet on the bottom of the frame. It makes a big difference in vibrations being transferred to a table/desk/etc.

The files for the pulleys and gears as well as the original instructions can be found

This is a really cool design, but wouldn't it be easier to use a DC motor instead of a stepper?

Definitely. But in my case it was easier to adapt the design for what I had lying around instead of buying an appropriate DC motor somewhere.

Congrats! Nice Job :)

May be this is a solution for all the folks that don't want to deal much with stepper electronics: https://www.reprap.me/easy-stepper.html

Very cool. Do you have any shots of your controller setup? I like the molex plug.

I don't have any pictures but it's just an Arduino Uno with an A4988 stepper driver. When I want to use the rock tumbler I can plug it in to the controller. When I don't use the rock tumbler I can disconnect the controller and use it to drive a different stepper in another project or prototype. I'm not a big fan of having to buy/build controllers for every project, unless it is something that I use very often.
