D&D Dice Cage

This is an update to last year's [dice plinth](http://www.thingiverse.com/thing:30584 "dice plinth").

I've added a printable cage to this model. Both pieces are interchangeable with their traditionally-manufactured Chessex ancestors.

I've done some experiments with a solid case made with clear PLA, but since not everyone's got access to that material I went with an open-celled cube.

The cage print is white ABS. You might try printing with a raft, but I find that spoils the smoothness of the top of the case (it's printed upside-down). A quick wipe with some ABSynthe will help a lot with adhesion.
