Machine rotary knob

A rotary knob for heavy machinery in bakeries, kitchens and the like. I created it as a substitute for a broken bakelite rotary knob on a kneading machine. It looks great in black ABS with 0.1 mm layers.
Included in the files you will find the OpenSCAD file of the original. Feel free to tweak, modify, hack the hell out of it to match the missing or broken knobs on your machines.
