Supports free end of drive shaft on Kossel delta. The original version made a big difference to my prints, I thought it was worth refining to make easier to fit. The main improvement is access holes to allow an Allen key to reach the motor bolts; also separated the fixing bolts and strengthened the cross bar.
As before, I have included a FreeCAD file, so that the hole for the 16mm bearing can be adjusted to suit your printer. The cutting cylinder had a radius of 8.08 for the .stl file provided, giving a firm fit. I have added some small spots of CA glue to ensure that the bearing is locked in place.
Tighten your belts with confidence, and be amazed how much it improves your prints
Fitting the support
Follow the instructions as before, but now its much easier to refit the motor bolts
Check carefully that the motor is rotating freely after all the bolts have been tightened down
