Holder for x20 SD + x20 microSD cards for ALL of your storage needs. Rugged, well protected 40 cards

Round donut-shaped holder/organizer/case for SD and microSD cards

It can hold: 1) 20 normal sized SD cards and 2) 20 microSD cards In total 40. You can also store microSD cards in SD cards adapters.

Tolerances are 0.2mm larger then cards themselves which for my printer worked perfectly.

I recommend printing the body with 0.2mm and the thread with 0.1mm. For my printer -Ender 3- 0.2mm threads were pretty rough and unusable really. For Base, thread starts at 25mm height. For Cover, thread starts from 10mm when printing upside down - both parts does not require supports. Threads has some extra clearance added on top of default Fusion360 clearances.

Top Cover screws onto the base closing safely all memories.

On internal side of Cover you can put a bit of foam to stop looser cards from wriggling around the case while in transport.
