Activated Carbon Filter Element

A simple no support required slotted jar I made to upgrade a cheap Fulminare H13 HEPA filter (filter type PU-P05/AC201B) by adding an activated carbon pellet element. Outer diameter of the jar is 62.75mm and the overall height is 99mm. You should be able to scale this up or down if required and i've included STEP and Fusion files if you want to make more significant mods. I designed it to fit snugly using 2mm EVA foam tape to seal it against the inside of the filter unit so the air is forced to pass through first the HEPA filter then through the activated carbon. I also cut out a piece of black activated carbon filter foam material and put it int he lid to help catch any dust. I used cheap carbon pellets from aliexpress and while it's not a magic solution but it certainly seems to have reduced the smell when I print things like CF-ASA, both while printing and also how long it lingers after. Overall a cheap and easy improvement which helps a $20 filter actually make a difference
