Air filter

I printed this air filter for the gas box in my van, which I`m turning into a camper. the gas box have to be isolated with an air exit to the outside (according to german law).
it has 2 parts from both sides of the car (I used it on the floor, but normally people used it on the side wall)
I Provided the stl and also the blend file compressed inside the rar with the lowpoly mesh and modifiers, so people could easly adjust it to their needs.
Could be also modified and used for different casing protection
