I liked the ideas for Gridfinity credit card holders that were already posted, but I had a slightly different use case, i.e., a shallower drawer, and felt it could hold more to maximize storage space.
I don't use a magnet system, so I rendered the original solid box without them. Then I used negative space boxes in PrusaSlicer to create the slots for the cards.
I am also creating a 13x small store card storage box 1x2x3. Look for it soon. 2024-03-21
