About this 3D model

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