Nano Sim Card Storage Box

thingiverse

We travel extensively, which means we frequently change SIM cards, resulting in the loss of our regular home SIM cards. All other designs I discovered focused excessively on slim design or multipurpose use (e.g., micro SD), so I created a box design that is small enough to store but not designed for a wallet. The slots are deep enough to accommodate two cards if you need more than 15 slots, which may appeal to certain individuals. A hole is provided to push the cards out, and it fits snugly around the SIM cards, preventing them from rattling and requiring a gentle push to remove them. Holes on the lid and front of the holder allow for the addition of a 10x2mm magnet to keep the lids shut. Given how tightly the slots are fitted and how well the lid fits, you can likely omit the magnet without encountering any issues. This design may prove useful to no one at all, but if it benefits anyone else, please let me know!
