Gridfinity SD Card Holder, 18 slot, 3x1

18 capacity, 3x1 Gridfinity, SD card holder.

Didn't like the tight spacings and stair-stepped designs I found before, so I made my own. All slots are uniform height, alternated for ease of access and intended to be just wide enough to read labels if you're like me and have tons of project cards that need to be identified quickly.

Intended to be used in a 3x1 3D printer sidecar holder. I've included a modified version of Voidstar Lab's Anycubic Chiron sidecar that fits this.
