Because the internal carbon filter box is quiet small and I already have a much bigger carbon filter with flex tubing and inner tube fan at hand, I decided to make this guy. Easy print, no supports. And due to the use of four strong neodym magnets you can turn it in any direction and there is no need to drill holes or whatsoever…

There are no screws. What you can see in one of the corners is one a magnets looking out because I broke the part by pressing it in to strong.

Magnets are 15mm in diameter and approx. 2.6mm in hight.
