5 x 8mm Rigid Coupler

thingiverse

For my Prusa i3 mk2s clone it was easier to not have integrated lead screws so I decided to make a rigid coupler to join the two together. You need a 4 m3x10 screws and 4 plain m3 nuts to hold each one together. This is intended to fit a 5mm shaft of a stepper motor that has a D shaft and a 8mm lead screw.
