Micro SD card fold out holder
thingiverse
Saw someone else's similar design and came up with this one. Bottom plate holes should be just right to thread in M3 screws, other pieces the holes should allow the screw to pass through. I laid the face plate on top of the top piece in Cura and then had it pause between layers to allow me to change the filament for two color. Face Plate is not needed, but handy to remember which side should be up when opening to avoid dumping your cards. **V2 update I added some __ V2.stl files that make the bottom and face plate have rounded edge for smoother feel in hand, added a small cut to the side to help push the trays out and increased the depth on Tray B to make it match Tray A and also allow stacking 2x cards if you need to store more than 8.
