Mississippi Queen piece
by randrews, published
The board game Mississippi Queen ( http://www.boardgamegeek.com/boardgame/256/the-mississippi-queen ) comes with player pieces that aren't well designed. This is a better design that accommodates two small six-sided dice (instead of the little stickered wheels).
Aside from that, it's an excellent test print: it should snugly fit two dice, it has thin walls, infill, can be printed in about 10 minutes, and if it's going to fail you can tell pretty early.
Looks great at 0.3mm layers and 20% infill, but feel free to tweak it however you want, it's a test print.
