MPCNC Air Assist for Creality 12v Laser (3030 Heat Sink)

thingiverse

Simple air assist attachment for a Creality 12v laser with a 30x30 heat sink, which is more like 28.5x28.5 in reality. I designed it for my laser to operate on my MPCNC Primo which only uses two screws to hold the laser to the mount instead of magnets. I don't know if it will work with the magnets still on or if you're running your laser on an Ender or CR10 etc. It uses a 5015 part cooling fan that just snaps in and it squeezes onto the laser with friction holding it in place. Works best with TPU but I have gotten one on that was made of PETG. I can't remember the optimal height for those lasers but I know it was around 70mm so I tried to point the air at the proper angle. The outlet is reduced from what the fan normally has so this may not be good for the fan long term, I'm not sure. When printed with TPU everything stays in place pretty well with just friction but I may do a v2 where everything is anchored in place with screws.
