For my Ortur Master lasers, but also for any other laser engraving machine with a 40x40mm laser diode, I have made an Air Assist unit that is very easy to install, and that gives a super good result.

The supplies for this Air Assist are:
- 2 printed parts (3D Prints)
- 1x 4mm screw, 20mm long
- 1x 4mm nut
- 1x Aquarium pump 150l / min http://gbe.st/302mgmV
- 1x air hose with aquarium pump
- 1x standard 6mm 3D printer nozzle

The Laser machines can be found here:
The big Ortur Master machine, in different power settings

And it's smaller brother, also in different power settings.

The files for the 3D printer can be downloaded FREE from my website. Print this with 0.2mm layer height, then the thread in the air pipe will fit perfectly with a 6mm 3D printer nozzle.
(Use E3D Style nozzles - I reused an old nozzle, that I replaced weeks ago)

My website with the download can be found here: 3d-printcreator.com/ortur-laser-master-15-air-assist-unit

Make sure that the 3D printer nozzle that you use for the air assist has an opening of 1 mm in diameter, so that the air can blow through it properly. I myself used an old 0.4mm nozzle, where I made the hole slightly larger with a drill.
