Printed part that snaps in place to keep the lead screw aligned in the middle of the Z-bottom hole assigned.
Takes care of the wobble in the Z-axis lead screw. (Check yours yourself, grab the z-axis leadscrew near the bottom and give it a wiggle, you’ll see what we mean).
Simple 10 second install, then it is print and forget. Problem solved.
Printed in Prusament Jet Black to match your Mini.
