A novel "ferris wheel" for SD card storage!
No supports required, 3 files, the stand, the wheel and the "plugs".
A FOURTH stl is included just for viewing, it's called DO-NOT-print-this.stl.
Don't print it!
I printed at 100% infill, because it didn't make much of a difference in materials or time, due to it's size.
it's possible that the SD cards could slip out, I think it depends on the printer you use. My final print had a few slots that were "loose" but once I put in all the SD cards they caused the other slots to tighten up because they "pushed" on the plastic between the slots.
Created in tinkercad, using simple shapes.
