This is a remixed rotary axis machine for use with a nema 17 stepper and a laser engraver to engrave round things. I am in process of printing it. Will update this when I finish.

FYI i never got this to function properly. It turns the objects just fine but they 'walk' Meaning they move forward and back in the y direction and not just rotate as the rollers move. Maybe it could be dialed in but I went to a chuck design instead. I am leaving the file up for posterity
