You know the feeling, where is that .... micro SD card. Anyway was always looking for the damned things, finding them back in the wast bin, locked under the wheels of my chair and even clinked to the bottom of my airtight filament boxes. Because I've got some trouble with my hands, the cards should by easy to pick out of the box. And because I also have to take them with me, I created a box with the cards standing in it like an old record. There's place for 14 micro SD cards and when the lid is on, they are secured in place by the lid.
