Wanted to convert my Multi-Sharp 2001 to a stand alone drill bit sharpener system, powered by a Bosch professional 12V battery. I used the motor, planetary gear and battery indicator from an old 12V drill (arbitrary brand). The gearbox can probably be skipped and replaced with a straight connection (not provided). Since this was based around some custom parts, it is more of an starting point than an easy plug-and-play print.

Source code (.stp & .3dm) is also provided, should you want to modify the design for your own purpose. Please share your prints!
