Customizable Corsi–Rosenthal Box

Corsi–Rosenthal Box air filter holder that is user customizable. Had to make this because I got some giant air filters I wanted to make a CR box out of. The tolerances weren't too good, but that's the beauty of customizable parts, is that you can tweak the tolerances. I'll just tape down the sides of mine :P

Just measure the width of the filter you want to use or use a width someone suggests in the comments. Plug it into the customizer to make your STL.

If you find a snug filter width value for a standard filter size, comment it down below.
