Cartridge storage - Atari 8bit and C64

thingiverse

These stackable storage shelves will hold Atari 8-bit (400/800/XEGS) cartridges snugly and accommodate most Commodore 64 cartridges, as long as they are no wider than 69mm. A 3x2 or 2x2 version is available. Keep in mind that a 2x2 shelf cannot be stacked on top of a 3x2 one. The fit between the shelves may be slightly tight, requiring some sanding to smooth out the "feet". A hammer might also help push them together, but results may vary and I make no claims or guarantees. In the example picture, the shelf is actually too deep, which prevents it from holding C64 cartridges. An updated photo will be posted later.
