5x5 Game Board With Ridges

I normally try not to upload things til I've printed them, but I don't have doubts about this one. It's an adaptation of a chessboard I made a while back, with the addition of ridges between spaces and a smaller grid.

I made it for variations on chess with rules including taking turns deploying pieces as needed, having no knight or queen, rolling dice to determine conflict outcome (1d6, +1 if not pawn, +2 for king, +1 if attacking), and pawns being able to attack backwards.(also pawns can't transform to other pieces, roll to see who places first, whoever places first plays first). I'm using dwarfs from http://www.thingiverse.com/thing:750403 and goblins from http://www.thingiverse.com/thing:57816 as pieces. I think for now I'll call it Skirmish: Dwarfs Vs Goblins, but for all I know that name and this game already exist. Also it hasn't been play tested, so try at your own risk.

(PS - yes I realize this could be played with a standard chess board and pieces, I just think this is more fun)
