Laser Air Assist Nozzle

thingiverse

To use with my affordable Chinese laser cutter, you'll require this print alongside a Pneumatic 12mm-1/4" BSPT male fitting. Print with two shells for safety; nozzle down orientation is recommended. After printing, heat the fitting while still hot to facilitate easy screwing onto the part. If it's too tight initially, quickly reheat and attach a preheated fitting. Seal and install as desired, FYI; you might need casket sealing or strips for a perfect fit.
