Originally designed to work with Opt Lasers cutting and engraving laser heads, the following file spawns a Laser Air Nozzle that can enable you to produce higher quality items during a laser cutting or engraving procedure. The nozzle creates a path for the airflow that can lower the temperature at the laser engraving or cutting site, effectively eradicating the possibility of potential defects. The defects it prevents include a randomized colour along the engravement, varying cutting depth, or a net of veins spreading from the engravement/cutting site. This nozzle was designed to work with the Opt Lasers cutting and engraving laser heads.
