NEJE 30W/40W air-assist nozzle

thingiverse

This is a printed air-assist nozzle for the NEJE 30W and 40W "new style" laser modules with the amber/red window. Simply replace the window with the nozzle part and insure the lens assembly is properly fitted into the cone. Attach a 6mm OD air-line from a ball-valve and compressor to provide air-assist coaxial with the beam. The "r3"-version accepts 3/8"OD / 1/4"ID vinyl tubing from the big-box store.
