Switch Micro SD holder in Switch Cart shape - fits inside the Cart slot

thingiverse

It's a custom Micro SD card holder that fits perfectly into your Nintendo Switch's game cartridge slot. This is particularly appealing to gamers who have already made the switch to digital games. Please note that while this design works, it could benefit from some additional refinement. If you take a closer look at the model, its limitations will become clear. It's also worth noting that even though this holder shouldn't cause any damage to either your Micro SD card or the game cartridge slot, it would be wise to carefully file and smooth out the edges where the 3D printer left excess filament.
