Yet another SD Card holder, because the world can't get enough of them.
I basically just made what I wanted because I got tired of looking and not finding exactly what I was after.
This little guy holds 5 full-size SD cards and/or microSD adaptors in the 5 rear slots, with the front slot reserved for microSDs (so that the lid will actually close, if you're into that sort of thing.) I'm guessing a minimum of 4 of the little guys in that front slot, but I only have 1 free right now.
Assembly is pretty obvious, don't be shy about carefully forcing it.
Do NOT print the "NOPRINT" .stl, because it won't work and then we'll all be sad. It's just there to make the nice picture of the assembled case.
Printed mine in PLA, other filaments may or may not size correctly.
I did 100% infill because it's tiny and you want the critical stressed areas (the hinge parts on both pieces) to be strong yet flexible for assembly. It's quite likely that other settings would work just fine but I can't say.
