After problems with focusing and tightening the bottom lens, I decided to modify the manufacturer's design on the AtomStack Hurricane a bit. Anyone who has this machine knows how complicated it is to tighten the lower lens on this laser I created a two nut model which will help you better fix the lens and tighten it better.

I have been testing my design for one month, it works properly I understand that different machines can have different variations so if there are problems I can adjust the model.

For full functionality of the modification you will also need the red part which is visible in the photos, this is because it changes the height of the autofocus Z.

Among the files are fusion 360 files should you need to modify the model.
