Here is the Z bracket for the stepper motor... there is a gap in one side of the stepper motor so its not completely flat on the frame... itps like 0.5mm gap so the stepper motor shaft has a deviation because of that..this bracket will solve that little issue.

U’ll need:

2x M5 TNUTS
2x M5 with 11.5mm length
2x M3 with 11.5mm length
2x M5 washer
