postcard holder
thingiverse
Use this to display postcards on a table. The design went fishy at some point, but I decided to keep it that way. Instructions It works also if you scale it down a bit. Layers will be visible at 0.2mm thickness. I think it's nice, but you may disagree and print as thin as possible.
