DungeonMorph Dice Grid

I bought the excellent DungeonMorph Dice http://www.dungeonmorphs.com/dice.shtml and I wanted a grid to hold them together after rolling.

I intend to make a 4x4, 3x4 and maybe even a 5x5 grid if I like this one.

If I knew more, I'd make a customizer... maybe a project for the future!
