SD Card Case (holds 12)

thingiverse

I design many cases that use 3mmx2mm magnets to secure the enclosure. These small magnets are inexpensive and easily obtained online. This simple case can hold up to 12 SD cards. Four magnets keep the lid firmly in place, while a few strategically placed tabs prevent it from accidentally falling off. The SD cards fit snugly inside, although the exact fit may vary depending on the thickness of your specific cards.
