A very simple SD and MICRO SD card holder made it for re-use my nintendo candy box coin.
Made it for re-use the Nintendo candy box coin that you can find at the Nintendo Official Stores or Amazon.
Or, you can also print your own Mario Box:

PS: Thanks to Caty for this amazing gif, the candys were great, but the box is even better!
Due to the form of the coin box, the holder moves inside the box, to fix that you can glue the holder to the bottom of the box.
