Using a Makerbot template and TinkerCAD, I made a makerbot chess set with each bot as the pieces. the knight is similar to Monty Python and the Holy Grail; no horses, just coconuts
Black, White or beige
Without any scaling, the bots can fit a chess board that has 1 inch by 1 inch tiles. The only one that mainly needs support is the knight, the others can survive without support but the shoulders may look a tad bit droopy. But if it is scaled big, use support.
Clean off support, and ready to play
TinkerCAD and changed the M to a: K for King, Q for queen, B for bishop, N for knight, R for rook and P for pawn. each one is characterized like the role they play as.
