HEPA filter for "aer" filters

Compact housing for HEPA "aer" filters that uses 60mm fan. Seals tightly, works well, real-world tested.

The back is flat with 3x M5 holes to secure directly to an enclosure wall.

Instructions: Print 5 parts. Print them with the joining edges on the bed as this will give you the flattest/most true surface when you try to stick them together.

I printed in ABS and used acetone to join them together.
Don't use PETG as you won't be able to join them with sufficient strength.
