Pokémon Box for Pokemon Cards with 3"x4" Toploader

Update - February 13, 2026:

Based on the various feedback, I have added a new version. This now has more tolerance, slightly more height for the cards, and the edges have been chamfered. This makes it easier to close the lid. The "old" version still remains. So you can choose which version you want to use.

I was looking for a box for Pokémon cards in 3" x 4" toploaders and unfortunately couldn't find one. Therefore, I took the original box as an example and completely redesigned a suitable box in Fusion 360. Thanks to the designer of the original box for the design. 
This box fits about 50 Pokémon cards with toploaders. The lid snaps into place.

As in the original, there are 4 parts on 3 plates in white, red, and black. The black ring is precisely designed and fits into the bottom shell with a bit of force without glue. Only the white button needs to be glued with a bit of superglue. The lid fits snugly on the ring and secures itself.
