QXZ Bowden Extruder

This is the bowden extruder I designed for my new CoreXZ printer (QuorXZ). I have included the necessary SCAD files if you want to modify it. It is designed to be mounted (without a spacer) to a Nema 17 motor through 6mm or 10mm MDF, or directly to a motor using one or both 5mm spacer(s) included. See instructions for necessary parts to build.
