Roomba 500 herringbone gears

thingiverse

This is just a remix of standard Roomba 500 gearbox gears to herringbone gears, which should be less noisy and should eliminate side forces. Print from high quality material - PA (nylon) prefered. Use reeeally low speed (10mm/s max) and 0.1 layer size max. When printed with nylon, warping is your enemy. Use brim (really hard to remove from gear) or print on paper with cores. After print it can be easily removed with water.
