3D Printed Chess: Cossack Pieces, a Travel Set and a Trophy King

“Cossack Era”

Six pieces in one theme, with the two sides differing only in colour. The king is a hetman in a zhupan with a sash and a hetman’s cap, the queen a berehynia in an embroidered shirt with a wreath of nine flowers, the bishop a hetman’s mace, the knight a Cossack horse with a mane and bridle, the rook a fortress tower with a gate and loopholes, the pawn a Cossack with a forelock.

Heights follow FIDE proportions: the king is 75 mm, the pawn 40 mm; a board with 45–50 mm squares fits. Each piece has a stack of steel washers inside: the king weighs 24 g instead of 12, so the pieces stand firmly like weighted wooden ones.

Magnetic travel chess

A box of two identical halves: open, it’s a 168 × 168 mm board with a–h and 1–8 notation; closed, it’s 186 × 92 × 42 mm with the pieces lying in slots inside. Every piece has a magnet and there is a steel sheet under the board: the pieces hold 30–60 times their own weight. We print the travel set in PETG — it handles drops and summer in a car.

A trophy king for tournaments

The “Cossack Era” hetman, scaled up twice, stands on a heavy pedestal with a plate. The plate carries the winner’s name and the tournament. For a club we reprint only the plate each year.

Limitations

• The “Cossack Era” set and the trophy king are PLA, which softens at 55–60 °C: don’t leave the pieces in the sun or by a radiator.
• The fine details — the cross on the cap, the horse’s ears, the forelock — aren’t for rough play.
• Small parts and magnets — not for children under 3.
