This is a model to attach an air assist to a NeJe laser module that I have on my Eleksmaker laser form banggood. It is printed in PLA with the tube on its side. The main body attached via the four screws on the top of the laser module, you may need longer screws. And the tube goes down the side with an M3 screw to secure it. I used some fish tank air tube from amazon, 5mm ID x 8mm OD Clear PVC Tubing, and connected it to a small paint sprayer compressor. It makes a huge difference with quality and performance.
