"Holds 4 full-size SD cards in a 1x1 Gridfinity square.
Awesomeness:
Why:
Other models I found all required frickin tweezers to get at the card you wanted, and launched the cards all over the room if you even thought about bumping them. This fixes both of those problems!
How 2 print pls halp:
The author remixed this model.

Fixed the tolerances to make the cards not fit not so snugly. Their design was well done, but one of the slots was much tighter than the others. I also found that all slots were just a bit to snug for my liking, meaning that as I tried to remove an SD card, sometimes the bin would come away with the SD card. So I just adjusted those few things.
I'll include @dswinton description, because he had it correct. Please go give him a like or a follow.
