I took a wonderful Storage Storage Box model and found it a bit small for my needs. So here is the extended version, which holds 12 microSD cards, 12 SD cards/adapters, and provides more space for miscellaneous items.

The tolerance was pretty tight in the original model; I could not push the cards into the slots, so I increased the tolerance. I made the clips a little bigger (contour offset set in profile) and removed the brim, as I found it unnecessary.

The model is set to be printed piece by piece, but you can easily change it. I also made it in two colors and added editable text on the lid.

To assemble the model, I had to expand the existing holes with a 2mm drill to be able to push the filament through. I used PETG for the hinges as it will not degrade over time like PLA, and fixed it with a hot knife. It works great!
