A simple box to store playing cards in.
Drawn in Sketchup, card symbols from the font "Symbols", embossed on surface using push/pull tool.
It prints well at .3mm layer height. There's a tight tolerance between lid and base for a good fit, but you may have to file/sand the overlap, depending how it prints for you. Download the STL files, slice and print. The Sketchup file is shared also should you want to modify.
Proving a popular item amongst my card playing relatives, so printed quite a few already!
Enjoy!
