Laser air assist, air bleed

Something i made for my own laser-machine, figured someone else might be interested so here we are.
I use it when i engrave ceramic tiles, but it most likely have other uses.

What is it?
A plastic pipe with small holes that bleeds out air to lower the pressure of the air-assist.

Why?
For when you need the lowest amount of air pressure just to keep the smoke away from the lens but not cool down the object more than necessary. Can be adjusted by covering holes with the tube.
