This is the design of Alex van Maarschalkerwaart in the FB Group "Atomstack X7 Pro Users Group"

This nozzle requires it's companion M5 Nut here: https://www.thingiverse.com/thing:5051175

Here is a youtube video showing the general application and other associated parts, like the 6mm Adapter for the Air-hose: https://youtu.be/QAjY6ir-oeY

The advantage to this nozzle, is there is no bending of the 3mm Brass tube as show in the video, it simply slides down the scre shaft and plugs right into this nozzle, making it super simple and easy. And highly effective.
