Roomba 500 herringbone gears

thingiverse

This is a reconfiguration of the standard Roomba 500 gearbox gears into herringbone gears, which should reduce noise levels and eliminate unwanted side forces. Print these gears using high-quality materials - PA (nylon) is preferred. Utilize extremely low printing speeds (10mm/s maximum) and a layer size of no more than 0.1. When printed with nylon, warping becomes a major concern. To combat this issue, use a brim or print the gear on paper with cores. After printing, it can be easily removed with water.
