HEPA adapter for 6" AC Infinity fans

thingiverse

I live in a dusty apartment and needed a way to filter the air for my enclosure. This is designed to fit over the backside of an AC Infinity vent fan such that the enclosure wall is sandwiched between the front plate and HEPA adapter. I used the following HEPA filter, but there's plenty of alternatives with the same dimensions: https://www.amazon.com/gp/product/B07QKT7DD9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 The basket is a tight fit to create a decent seal around the filter, but the spiral design gives it a bit of spring to maintain tension. I have 2 on my setup, one in the lid that pulls air out and one in the base that pushes air in. I've included a simple, slim profile diffuser plate for the input to prevent it from blowing directly on the printer.
