This is a SD card holder for six SD cards and another six micro SD cards. A save place for up to 12 TB of data ;-)

If you need a storage for only micro-SD cards you should have a look at a smaller version: https://www.printables.com/model/410385-micro-sd-card-case

See also the threaded jars without SD card slots: https://www.prusaprinters.org/prints/29293-threaded-jar
Or a portable smell save ashtray: https://www.printables.com/model/232262-portable-ashtray

After printing you should screw the jar and lid back and forth and clean the thread with a tissue a couple of times, in order to grind the thread in and make it rotate smooth. The longer you screw, the smoother it gets. If you can't turn the lid, try printing it just a touch bigger. 101% for the lid seems to fit on most printers. Or consider to calibrate your printer. ;-)

Blender file (v2.92) included. Probably you want to add some inprint to the lid.
