Tr8/2mm Z coupler 4 start

thingiverse

I'm rewriting the text as follows: You'll need a Nema 17 5mm Z-Axis coupler that fits perfectly with the TR8/2 Z-Axis four start configuration. To assemble it, you can simply use the parts without requiring any screws or glue - although if you prefer to secure them in place, you can easily do so using M3x4x4 brass inserts.
