Didn't like the OG SD card holder so I made something more accessible, but easily sortable. Uses the M5 nut insert. Holds 20 micro SD cards and 10 SD cards. The cards fit a little loose, especially the MicroSD cards but I made it that way so they're easy to grab. I printed mine with 0.2mm layer heights but definitely can go higher. No supports required.
The author remixed this model.
