NEMA17 Stepper motor spacer
thingiverse
I'm modifying my Replicator clone by swapping out the Z axis for a threaded rod that's 3cm longer than required, which necessitates lowering the NEMA 17 stepper motor secured to the bottom of the printer. This spacer is specifically designed to achieve this adjustment, providing approximately 3.5cm of clearance - coincidentally matching the typical height of a standard stepper motor. Modifying the length to suit your needs should be straightforward in Blender. I've overlooked the size of my chosen coupling and have now added an updated version with a circular cutout on one end.
