The file 'Air Assist For Laser Cutter V2 3D Printer Model' is (stl) file type, size is 499.7KB.
In addition to my first version of an Air Assist, here is a improved version.
with my first nozzle the Air came from one direction and when i cut in the opposite direction of the Airflow there was again visible fume.
with the new design, there are three nozzles.
the airflow meet about 4mm above the cutting surface and blow as one prependicular onto the cutting area. Air Assist was designed for a 2" Lens. I think 2,5" will also work, but 1,5" I think the it is to big. When i get my Lens-Kit I'll try and put the results in here. Maybe I'll create a extra version.
see the example cut.....
my printer couldn't print perfectly the 1mm hole in the nozzles so i cleaned them with a 1mm drill bit
