NEJE A40640 module axial air assist
thingiverse
3D printed axial air-assist addon for NEJE A40640 laser module. For connection to the compressor used an airbrush connector with 1/8 thread. Better use clear red resin I think. Added part "NEJE A4060 module cooler air duct". Just for a "clean" air supply. But requires a separate pneumatic line from compressor (perhaps with lower pressure than in the air assist part). Added "neje A40640 axial air assist_sh" - shorter variant for deeper cuts. I also made wider holes (ray in and nozzle) cause it looks like they are not exactly coaxial with an optical axis. I can't disassemble the module for more accurate measuring, so I decided to make bigger holes (though it's not a very good variant).
