HEPA Air Filter Remix 120mm Fan & 86889 Filters

This is remix of MQ1991's HEPA filter system. https://www.thingiverse.com/thing:1831932 Many of the parts I used I found on Cybertron3D's Lack enclosure part list. https://www.thingiverse.com/thing:3374299 I flipped the direction of flow and added a chamber for activated carbon pre-filters. the pre-filter chamber is secured to the filter funnel using m4 screws. The base has 5mm holes for mounting. I used hot glue to seal the base to the top of my enclosure in addition to the screws. There is the option to secure the base to the pre-filter chamber with 3mm screws but I do not find it necessary. I have also created a fan vibration dampener and gasket that I printed in TPU to add between the fan and the filter funnel. - 86889 Filters https://www.amazon.com/gp/product/B07BHDCFYC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 - Activated Carbon Pre-Filters https://www.amazon.com/gp/product/B074MKZNFW/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 - 120mm
