Mi Robot Vacuum-Mop P front wheel

thingiverse

The presented model is a replacement for the front wheel of the Xiaomi Mi Robot Vacuum-Mop P. I designed this wheel because the original one kept getting blocked by hair and pet fur. In my model, the wheel is narrower, so the hair doesn't wind around the axle and block it. The wheel consists of two symmetrical elements that need to be glued together. Inside the axle, there is a 2mm wide hole where a metal wire should be inserted for reinforcement; in my case, it's a pin cut from a rivet. The model also features 2mm x 2mm grooves where I placed rubber O-rings for better traction, although they are not required.
