Print Head V3-1-0 Shaft Coupler Adapter.stl

This is a fairly hacky and experimental part that couples a typical "plum" style shaft coupler to a roughly 8.5mm hex shaft, the size that most wood augers have in the USA. The stepper shaft is 12mm, but I couldn't find a corresponding coupler for the auger side, so I just cut this part in 1/4" plywood, and it works just fine.

All Extruder Parts Layout.svg

This is the most recent layout for all of the wooden spacer parts required to build the Trash Printer head. They are designed to all fit in cut-area of a Glowforge Basic laser cutter, which is about 10"x19". Any CNC router or laser cutter should be able to cut these parts, or if necessary you can print these out and fabricate them by hand. I'm using 1/4" plywood. The lower parts act as a heat brake between the extruder barrel and PVC hopper, and so it's best to use wood for these, as plastic parts may melt or creep. The upper spacers can be 3D printed or laser cut in plastic or wood.
