CR-10 / CR-10S Z Axis Spacer

thingiverse

It's not rare for a CR-10 or CR-10s to arrive with a Z axis that's slightly out of whack. This can sometimes cause your Z screw to get stuck or jump around, leading to some serious frustration. The problem lies in the way the stepper motor is mounted directly to the chassis, using an injection-molded part as seen in this attached image. Unfortunately, this setup can pull the stepper motor too far back from its proper alignment with the gantry in a few cases. This 3mm spacer comes to the rescue by nudging the stepper motor outwards away from the chassis and back into perfect alignment. I'm happy to modify the part for different spacing needs - just ask in the comments section if 3mm isn't quite right for you. You'll need some longer M3 screws, though.

To ensure the part's stability, I've built it with five layers of strength on top, bottom, and walls. Plus, it'll be screwed into place from multiple directions for extra security.
