myminifactory

This is an 8mm spacer for Nema 17, required to attach this coupler to the Geeetech I3: http://www.thingiverse.com/thing:225753 Coupling it with thing:1904968 eliminates all z-wobble issues and provides perfectly smooth prints. Although aluminium spring couplers still produce a minimal amount of z-wobble, oldham couplers prove to be an excellent alternative worth trying out! To make this work, you'll need the following components: 8pcs M3x20mm screws to mount the Nema17 with spacer 8pcs M3 nuts for the oldham coupler 8pcs M3x6mm headless pin screws for the oldham coupler The shaft of the Nema17 was shortened to a length of 10mm.
