This is an upgrade for you Prusa Mini to use M10 pneumatic fittings with the existing brass threaded fitting on the hotend and extruder. The exterior of the coupler is hexagonal which will allow for a wrench to help seat it against the pneumatic fitting.
I kept getting issues with the ptfe backing out of those brass barbs originally on the ptfe tubing as they are only good for one use. Switching to the pneumatic fittings has proved to make troubleshooting much easier and overall feels like the better option.
Material: Galaxy Black PLA [PETG would work well also]
Layer Height: 0.15mm
