I liked the idea of the pazzled pen Holder but i wanted to organize my SD Cards and USB Sticks too.
So this is just a remake of the 20 mm Original with some slots for Storage Cards and USB Sticks.
It will fit:
4x USB Stick
8x SD Card
6x MicroSD Card
If you need another slot configuration like only SD or more MicroSD or what ever, contact me :)

Infill doesn't matter here because all walls will be solid.
