Roomba Side Brush Gear

thingiverse

I designed this model for the plastic gear in the Roomba side brush assembly, which fails to function properly, but works perfectly for my 600 series Roomba.\r\n\r\nAfter numerous unsuccessful attempts with other models, I chose to create my own. Printing it with a smaller nozzle (0.2mm proved effective for me) results in better and smoother running gear teeth.
