When adapting this piece of hardware into your design, make sure to allow for a bit of axial play in both directions, in order for the filament path to retain some level of self-correction. The bearing facing the motor face should have about 0.4 mm of material between it and the motor face in order for the plastic gear to retain as much engagement as possible.
