gear for LEGO DUPLO train motor
thingiverse
Often cause damage of trains Lego hollow - split gear on the motor shaft. This is not a problem, if you have a 3D printer. Especially for repair of my locomotive I modeled this gear. Gear must be worn tight on the motor shaft. To put the gear on the shaft, I wasted edge of the inner hole of printed gear a little by using stationery knife and push it onto the shaft with force.
