33mm Air Assist Nozzle

thingiverse

Air assist nozzle for 33mm diode laser. Accepts 1/4 in OD hose. Uses three (probably optional) o-rings. Two 1/4" x 3/8" x 1/16", and one 9/16" x 3/4" x 3/32". I got mine from a nitrile o-ring assortment kit from Harbor Freight. Two smaller o-rings go into the connection for the 1/4" hose, and the larger one goes between the nozzle and the laser module. Attaches to the laser using M3 screws. I had to tap my laser. 55mm length for a 60mm focal distance.
