I have a ton of sd cards and micro sd cards probably over 30 that I use regularly with all my cameras, FPV, 3d printing, photography, go pro, cell phones, drones, TV's, etc. The micro sd cards are too small to write much on and you can't put a label or sticker on them because then they don't fit or they get sticky adhesive on them which can gum up your devices sd slot. So I was looking at SD and Micro card holders online and I thought . . . It would be nice to be able to label some of these cards so I can organize what they are being used for. So I designed this. The intended purpose is to store a micro sd card in a SD card holder or storage device but have room the put a small sticker, label, or even sharpie on it so that I know which is which. Many of them are the same brand and size. Anyhow, I'm rambling now. Print at high res as the notches that keep the little guy from falling out should be pretty precise in order for it to work as designed. Plus, it's not big. Even at high res, they don't take long. I printed 4 at a time with no issues at .175mm res. that's an MP Select magic number btw. Happy printing!
