I used TinkerCAD to cut out the 10xMicroSD slots and the 3xSD card slots, then created my own case to contain 12 full size SD cards, 20 micro SD cards, and at least 2 USB thumb drives. This case was designed to contain a USB card reader along with several cards and this was the most useful way I could see to accomplish it.

This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/dk3jBXwfsyz
