Atomstack A5Pro Air Assist

Direct replacement for the viewing window on the Atomstack M40 laser module.
Please note the window is held in place with an M5 grub screw. This screw is also used to secure the air-assist nozzle. I replaced the grub screw with an M3x8 socket head cap screw for toolless changes.

As always wear high-quality laser eye protection and be safe.

UPDATE 28/11/2020:

1. Feedback from a Maker comment it appears there is at least one other version of the AtomStack M40 laser module having a 21x26mm cutout vs. mine which is 29x26. A new model has been uploaded please feel free to try and comment if you like or would like to see changes.
2. Added revised more compact 29x26
