HEPA filter case for chamber fan exhaust P1S/X1C

HEPA filters for Samsung SC4300 / VC4300 series vacuum cleaners are widely available (you can find links for Amazon and Aliexpress searches below) and fairly inexpensive (less than 2€/pc). The filter is 110x125x20 mm, it is slightly larger than the exhaust grille (which is 100x90mm). The filter also includes a rubber gasket on one side that is pushed against the back plate of the printer. The case is held at place with 6x3 magnets, simple to intall, no tools needed. As a side effect you can also reduce the exhaust fan noise.

Use superglue to fix the magnets into the pockets at the four corners.

As the case is outside of the printer you can use any material you like: PLA, PETG, etc. No supports needed.
