About this 3D model

This is a replacement part which allows to install stepper motor dampers on a Geeetech A20M (and maybe other printers too). Since the motor has the same orientation as before, there's no need to invert the motor's direction in the firmware. It's mostly the same part as the original metal part, but the motor is offset since it's gear pulleys are press-fitted and cannot be moved to make up for the offset caused by the dampers.
