MicroSD Card Case (REMIX) - A and B Side Caps

This a remix of "geartechbrandon" - "MicroSD card case". I'm creating a Raspberry Pi Lab and I needed a way to keep a bunch of MicroSD cards with the same OS separated. I saw "geartechbrandon" MicroSD card holder which looked perfect for the task, but I had no way to tell the difference visually where my cards were, so I modified the cap to have a A and B side to tell the difference. Yeah i guess a labeler would have done the task but that's not fun!

I only have the modified caps posted here,
