Activated Carbon Filter Box with magnetic lid

I had had several time which rotten ingredients causing bad olour in my refrigerator then i usually bought an small carbon filter, but I thought Why dont make my own filter, that can be refilled any time? 

EDIT July, 7 2025: Forget to mention, it uses 8 pcs 5x2mm magnets

So I designed this and sharing now after months using it myself.

I shared the 3mf file with my config for the Lid you need to change to your printer and profile.

This can be printed in any material you want, mine was printed in PLA 0.2 layer height 

The lid was printed with a modifier solid (generic torus) with normal config and the center of lid without top/bottom layers and 4 perimeters

I shared the 3mf file with my config for the Lid you need to change to your printer and profile but if you want to do yourself can follow below pictures:
