I printed the parts for a planetary gearbox from a Thingiverse download, then attached a stepper motor and reversing drive to it. Danged if the thing didn't work! Comment below for more info.

The Thingiverse page was WE R2.4+Six Axis, but it appears to have been taken down. I have a zip file of the assembly in SolidWorks, if you'd like?
