Roomba side brush gear

thingiverse

I modified this because the original didn't fit quite right--it had too much wiggle, and the gears didn't grab together right. I never did get this to work though--I suspect that it may be that my motor is burned out also. If your motor is working correctly, I bet this will be just fine for you, which is why I am sharing. I model in Lightwave, so I am sharing that file also, but I originally just imported the other STL file to start with. Changes are: * The gear is a bit shorter in all--I found it was too tall for the gear housing * The bottom gear is a bit wider, to couple better with the motor's gear * The top gear is a bit wider also, but by a bit more, to couple better with the other nylon gear * The shaft hole is wider, so you won't have to drill it out post-print
