A complete set of 32 pieces from one number. Set the king height and every other piece follows at the classic Staunton ratio; the generator checks the base diameter against your board and tells you whether the set will actually fit the squares.
Two styles: classic, with the collar and bead that give a piece its shadow line, and minimal, with plain surfaces that print cleanly at small sizes. Both are bodies of revolution – no supports, no overhangs, no cleanup.
A set is 32 pieces: per side 8 pawns, 2 rooks, 2 knights, 2 bishops, 1 queen, 1 king. You only need the six type files – the quantity is set in the slicer. Two colours, two print runs.
You set one number: the king height. Every other piece follows from it at a fixed ratio – queen 0.87, bishop 0.75, knight 0.72, rook 0.60, pawn 0.50 of the king. That is the proportion used by the common Staunton sets, and it is what makes a set look right rather than like six unrelated objects.
The second number is the base diameter of the king. The rule of thumb for a available set: the king base should be about 78 per cent of the board square. The generator checks that against the square size you enter and says plainly whether the set will fit the board – before you spend twenty-six hours of machine time on it.
| 85–105 mm king | FIDE tournament range. Board squares 50–55 mm. |
| 76 mm king | Club and home size, the default here. Squares 40–45 mm. |
| 60 mm king | Travel and small boards. Squares 32–35 mm. |
| Below 50 mm | Printable, but the collar and bead detail disappears in the layers. Use the minimal style instead. |
Print upright. Every piece except the knight is a body of revolution standing on its own base, so no supports are needed anywhere. The knight's head is a profile and prints cleanly at 0.12 mm layers; at 0.2 mm it turns into a lump.
The recess in the base takes washers, coins or casting resin. A weighted piece feels like a bought set and costs nothing extra in filament. Make the recess 0.3–0.4 mm larger than the insert and glue a felt pad over it.
A full set of 32 pieces fits on a 256 mm bed in one go – that is roughly 142 g and a working day of machine time. Print the two colours as two jobs, not as one with a filament change.
