My seven year old is now collecting chess sets. I have a bunch of BNC connectors laying around. So here is a BNC chess set. There are two versions of the pawn.
Skeinforge may complain about the king and or queen, but I ignored the errors and they print fine. I'm not enough of an expert to find and fix the dangling participles. Have fun.
Update: added a mock bnc connector for those who are connector deprived. It is not dimensionally correct, nor functional, but it should work as a replacement in this chess set. You probably only need it in the knight, pawn and bishop pieces.
Print the appropriate number of chess pieces.
Drill the holes out to fit your connectors.
Insert BNC's into plastic pieces.
Lather, rinse, repeat.
