Hollow Dice Set

A set of dice that you can snap together after printing and wrap around marbles, rocks, other dice, etc.
Files ready to print. Full die, as well as just the numbers and just the frame for dual printing.
Thanks to http://www.thingiverse.com/mathgrrl/about for the basic (though not simple) design.
