Filter for laser engraver exhaust

I attached a Creality Falcon2 pro 22w laser engraver to the workshop ventilation system and didn't want small ash particles to get into the pipes. That's why I designed a small and simple air filter for the engraver

Easy to attach to the exhaust fan, may also work on other laser engravers.

Filter i used is from amazon.de

Nothing else is needed. The original bolts work.

I don't know if it works well, but as you can see from the pictures, it filters something and gives me peace of mind.
