Ortur Laser Master 2 20W Fixed Focus air assist
thingiverse
This is to add air assist to an Ortur Laser Master 2 - 20W fixed focus laser. This uses 1/4" airline more common in automotive air use instead of aquarium tubing. It was easier to connect to my compressor since I had a line there for my CNC. It prints in two parts using three M3-16 screws and M3 nuts. I added a piece of 1/16" balsa wood as a gasket but probably isn't necessary. I had is sitting there. Chances are if you own this laser you probably do too. I super glued a 3D nozzle to the bottom part after drilling the hole to 1/16" I also added an air hose guide. I updated my laser module to a 40W Pro Chinese model and it fits as well as the Ortur one.
