Remixed Michael303's design, I couldnt get the other tool to last more than a single use with PLA+ or PETG.

This design uses a single M4x15mm screw, thread it into the hole and voila (tap recommended).

.4 or .6 nozzle
PLA or PETG
99% infill recommended, but >50% should be fine
8 walls/top/bottom layers - 5 minimum if printing w/.6 nozzle
