Stepper Motor Shaft Coupler NEMA23 6.5mm Bore
thingiverse
This part slips on to the shaft of a NEMA23 Stepper Motor with a 6.5mm shaft. There are four 6.5mm holes at the 12-3-6-9 o'clock positions for bolting something on. Set screw holes sized for 8-32 are at the 1:30 and 7:30 positions. To ensure a properly sized hole, they are printed undersized and need to be drilled out. I use this metric drill bit set from Amazon. Print Settings Rafts: No Supports: No Resolution: 0.5mm Nozzle, 0.1mm Layer Infill: 25% Notes: Sliced with Cura 15, printed on a hand-built Prusa i3.
