Dummy NEMA 17 motor (shaft mount)

thingiverse

I decided to modify my Prusa I3 clone to use only one Z-motor, driving the other leadscrew with a belt, so I had to remove the extra motor. I designed this dummy motor to replace it perfectly. It uses two 5 x 14 x 5 mm bearings and a 100mm long 5mm shaft for a dual shaft NEMA equivalent motor. Also required are four M3 nuts and longer M3 mounting screws. I have supplied two top bearing retainers of different thicknesses. These adjust the overall length of the 'motor', which has a nominal length of 48mm.
