Snapmaker U1 Hardened Nozzle Holder

This insert was designed to fit with the 6x3 single height drawer from the Gridfinity Rugged Drawer system.  Designed to fit fairly tightly within the drawer so depending on printer tolerances this may need to be scaled down a percent, but fit tightly and fully as it sits for me.   The Drawer is cut into objects for easy layer level color changing , requiring only 2 filament changes.
