There are some nice ideas for air-assist. Science I have all the parts, Solidworks, and 3D printer I designed my own variant where you use a stock cone and put a new one outside it.I also designed a holder for the hose where the center of the hose points in the center of the laser beam, 2mm from the head body.8 prototypes later and it is ready for testing.BTW. The hose has the correct outside diameter but the wrong inside. I use it just for testing.
