Air Assist Girdle for Laser Cutter Nozzle

blackTooth laser was missing nipple to allow air compressor line to connect with air assist nozzle.

This thing is a "girdle" that press fits onto the nozzle cone, and allows the air hose to friction fit nicely.

TIP: I used ABS and after printing I quickly removed the support material from inside the coupling for the air hose to connect, then push/snap fit it onto the nozzle before the ABS had cooled and contracted completely.
Now it "snaps" on and off quite nicely.
