Neato Botvac Lidar Drive Wheel

thingiverse

The drive wheel on my Neato Lidar was loose so the lidar (Piccolo Laser Distance Sensor) didn't spin up properly. I suspect this is why the motor went out -- PWM trying hard to get the RPMs up while the pulley slipped and slipped. This pulley fits the motor shaft tightly and diameter seems to be close enough for lidar measurements to work well. Note that the channel the belt runs in isn't quite the same shape (this one is wider), but it works well. The 3D printed one isn't as smooth as the original, giving more surface grip but less sidewall. Anyway, it works.
