Laminar Flow Air Assist Nozzle for Ortur Master 2 with fixed focal length (Remix)

thingiverse

This Remix of the brilliant original design aims to eliminate a few minor issues that I came across after printing. 1. I found that the original nozzle was to long and would be to close to the material being cut, thus hindering the laminar air flow. I also found that the length of the original nozzle was almost the same as the focal length of the laser, which meant that I would have to cut with the nozzle almost touching the material in order to get good focus. Therefore, I shortened the nozzle remarkably whilst trying to conserve the Laminar flow aspect. 2. I found that with the nozzle installed, there was no good way to focus the laser with the aluminum cylinder. So I flattened the air intake arm of the nozzle and moved the surface so that it would sit at the same height as the bottom of the Lens. 3. I modified the air intake arm to safe material and to fit a 5.5 mm hose.
