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) without the need to reverse the motor's axis in the firmware, since the motor still has the same orientation before. 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.
