Nema 17 spacer 8mm for Geeetech I3

thingiverse

This is a custom-designed spacer for the Nema 17 motor, enabling users to mount this coupler to their Geeetech I3 3D printer: http://www.thingiverse.com/thing:225753. By combining it with this thing: http://www.thingiverse.com/thing:1904968, users can effectively eliminate z-wobble and achieve ultra-smooth prints. The aluminium spring coupler still introduces some residual z-wobble, prompting me to try oldham couplers instead - a decision that has proven well worth making! To assemble the system, you'll need the following components: * 8 M3x20mm screws to secure the Nema17 motor with the spacer * 8 M3 nuts for mounting the oldham coupler * 8 headless pin screws (M3x6mm) to fasten the oldham coupler The shaft of the Nema17 motor was carefully trimmed to a length of 10mm.
