This is a simple print-in-place 4x micro SD card + 1x SD Card wallet that is easy to customize with a logo of your choice. In this example I've emblazoned a dragon on the back in a couple colors. Blank included as well so you can customize your own!
Little finger push-outs designed so that you can pop the cards out. Note that tolerances may vary slightly depending on which filament you choose. This has been tested in PLA/PETG, but if you have any fit issues try scaling by +/- 0.5%.
