Z Rod Collar- 8mm Collar (M3 Screw)

thingiverse

This is a collar, that clamps to your z rod and secures it above a pillow bearing or bearing block. This removes the load from the motor shaft and places it on the motor body. This helps with alignment and Z rod wobble. There is a flat model, that prints without supports and will require a simple metal washer to rid on the bearing. A second model is there, with an integrated spacer. This prints without supports and removed the need for a washer. The model uses a small M3 screw and an M3 nut.
