In a previous design for an air filtration system I had to cut away into the plexiglass in the lack enclosure and added a screen material for the charcoal pellets. In this design I used the Infill percentage removing top and bottom layers in the base and tray to create a permanent screen filter. The fan mount is the only piece which requires hardware Bolts and Heat Sets, the air filter stays in without the cover which is attached with magnets, everything else is interlocked, press fit or held with a printed screw.
