Low profile Air Assist Nozzle for Ortur Master 2 20W 2021 fixed focus laser

prusaprinters

I saw plenty designs for an air-assist nozzle. None of them have the nozzle so low that it also shields the laser from your eyes. I ASSUME this will be a lot safer for your eyes when you are working with it turned on in the room. I still advise to use protective glasses when looking directly at it Disclaimer: USE AT YOUR OWN RISK. Lasers are cool but can harm you. I have the 2021 20W fixed focus Ortur Laser Master 2, which has a positioning block to set the correct focus. This nozzle is designed to replace that 30mm focus block; I designed it to be 28mm when inserted fully onto the laser. Designed at a little over 12mm for a snug fit; you might need to sand a bit. Air assist opening assumes a 6mm outer diameter tube. Be sure to test if you have enough airflow before starting a cut.

See last photo (bottom view) Else you will get support in the air-hose opening, which you cannot remove. Cura has a great plugin for this (Custom Supports, by Krasimir Stefanov) Category: DIY
