Summary

I really like this design. I think it is very clever.

I need tweezers to get the micro cards out, but it is very compact and sturdy. A good storage solution.

I printed this out in ABS and PLA on 2 different printers and I had a hard time getting the adapter card out on both so I remixed it.

I opened up the top slot a tiny bit and got rid of the locking nub. The adapter card still stays in place, but I can get it out without destroying it now.

I made another remix, I gutted out the box, turning it into a small storage box.

While I was at it I designed a tray to hold 3 of these boxes in a row.
