Altoids Tin Micro SD Card Organizer Insert

thingiverse

Holds 25 cards! It's a bit of a snug fit to get it past the lip, but once it's in, the pip will hold it in place. Because of the lip, there is a little wiggle room once the insert is fully seated. If you think this will bother you, just add a bit of your adhesive of choice to the bottom of the tin beforehand because once it's in, it's SUPER hard to come out. I just used a small dab of 2 part epoxy on the second one that I made and it has been holding up well.
