Printed in PLA .4 nozzel, .2mm balanced, 15% infill, auto supports.
Supports are only needed for "Filter3" file. It doesn't matter if you print on the bottom or top. Both ways take the same time and use the same amount of supports.
Designed around this specific filter (Aff): https://amzn.to/4tJ3SqA
Charcoal filter sheets (cut with stencil) (Aff): https://amzn.to/4taNYW6
Magnets (Aff): https://amzn.to/3OidWHV

Materials:
ONE HEPA Filter: 100mm x 150 mm x ~16mm
TWO Charcoal filter sheets: cut to 100mm x 150mm. Stencil included.
SIXTEEN Magnets: 6mm x 2mm
Print Filter3 and FilterMesh. Print FilterStencil if you want.
Press fit (I used channel locks) the magnets into each magnet hole. Ensure proper orientation.
Install HEPA filter with gasket facing the magnets(out) and the arrow flow direction pointing away from the magnets. This is a tight fit. Be sure to push the filter in as far as it will go. There will be <1mm of gasket extended past the filter box. The magnets will press this into the printer helping to create a seal.
Cut two 100mm x 150mm pieces of carbon filter. Stencil I cluded. Stack these and insert into the chamfer on the other side of the filter.
Press the FilterMesh aligned properly over the carbon sheets. This is another tight fit. I put the FilterMesh side on a table and pressed from the other side of the filter.
Place around exhaust vents. DONE!
You will want to play around with fan settings now that you have added resistance from the filter.
I might increase some tolerances for both the HEPA and the FilterMesh to make removal and installation easier. However, you can easily install the carbon filters from the other side and never remove the FilterMesh.
