This is a pocket sized SD card holder to keep your micro SD cards from going missing. I print it in bright colors like high viz green or orange to keep it from disappearing. There are side pockets to put extra stuff into but it will not fit a full size SD card, I put notes (22mm x 18mm) to myself in these to remind me what the cards are for: action camera, documents, backup firmware, etc.

No supports needed on my crappy CR10s in PLA
