Just as the name implies, StarCraft Chess. An all-race at once chess set based on StarCraft. I have made 3 new things that are chess sets for each individual race.
Thanks to Zhall I found all of the units I needed, thank you Zhall! There is also a marine and a zealot for a pawn if you want it, and in that case you can replace the Viking or the Stalker with a mutalisk or a roach to balance out the number of pieces each race has. These should be the correct size for chess pieces now. There is an articulated version of the Viking here http://www.thingiverse.com/thing:598121 and the Stalker here http://www.thingiverse.com/thing:2146937 if you want them. If anyone has made articulates of any of these please speak up! Unfortunately I cannot really scale the articulated Viking to be the size of a chess piece.
