Arkham Horror (LCG) Storage Box Organizer with the Mansions of Madness box (Only Perfect Size Sleeves)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4039075.

I use the empty Mansions of Madsness box (285x285mm) To save PLA and lighten this storage, I only use 1 line for the walls (270g for the biggest part). These designs all assume no sleeves or perfect size sleeves on these cards.
