Hepa Filter housing / holder

I created a holder for a hepa filter as I want to print different materials.
It will work for any housing and can be attached with M4 screws

The holder/housing is made for following Filter from Ebay:
Active HEPA-Filter SF-AH 50 für Miele Cat & Dog 5000

calibrate your printer first and you will get a nice fitting hepafilter housing
