Luxury Imperial Chess Set, Modular Board - The Citadel 3D Model

The Citadel is an imperial chess set in which the army is a fortress: every piece stands on an eight-point star-fort base and rises in lamellar armour, with a gilt belt and an imperial seal on its cuirass. Six original piece designs make a full 34-piece set, completed by a modular 600 mm board, "the Rampart".

WHAT YOU GET
- 6 print-ready piece designs: King, Queen, Bishop, Knight, Rook and Pawn, each in STL, 3MF and OBJ (print each design in two finishes for the white and black armies)
- Modular board: 16 modules in STL, 3MF and OBJ (field tile, square inlay, 4 corner and 8 straight frame pieces, butterfly key, foot)
- Print & Assembly Guide (PDF, in the Board archive): quantities, print settings, stone list, weighting and board assembly

SIZES
- King 110 mm (base 54 mm across the bastion tips), Queen 100 mm, Bishop 90 mm, Knight 88 mm, Rook 82 mm, Pawn 62 mm (base 34 mm)
- Board 600 x 600 mm with 64 mm squares: 16 field tiles, 64 square inlays, 12 frame pieces with a star fort on each corner, 52 hidden butterfly keys and 4 optional feet

FILES IN THE DOWNLOAD
One ZIP package that contains:
- Six STL archives, one per piece design (King, Queen, Bishop, Knight, Rook, Pawn)
- Board archive: the 16 board modules (STL) and the Print & Assembly Guide (PDF)
- One 3MF archive and one OBJ archive with the same files in those formats

PRINT SETTINGS
- Every file is a closed, manifold single shell with outward normals, in millimetres; the pieces have flat bases
- Printer: high-resolution resin (SLA, MSLA or DLP), XY 50 microns or finer. Tough or ABS-like resin for display pieces, castable resin for lost-wax casting
- Layer height: 25 microns for final prints, 50 microns for test prints
- Orientation: upright, base flat on the build plate, exactly as modelled. A 0.6 mm foot chamfer absorbs the first-layer bulge
- Supports: none needed. Downward-facing surfaces rise at 46 degrees or steeper; only the Knight's chin (about 30 degrees) may want 2–3 light supports
- Quantities: 2 Kings, 4 Queens (one extra per side), 4 Bishops, 4 Knights, 4 Rooks and 16 Pawns, half in each finish
- Stones: one calibrated cabochon per piece (oval 8 x 6 and 7 x 5 mm, round 5, 4 and 3 mm) and square calibré stones for the King's and Queen's belts; the full list is in the guide
- Weighting: glue a steel or tungsten disc into the bore under each piece and cover it with a felt pad (tungsten recommended for the Rooks)
- Board: tiles and frame in SLS (PA12) or on a large-bed FDM printer (0.4 mm nozzle, 0.12–0.16 mm layers, top face up, no supports); inlays, keys and feet in resin. 52 butterfly keys join the modules
- Print a Pawn first to tune exposure and fit

Full details are in the Print & Assembly Guide (PDF) inside the Board archive.

PLEASE NOTE
All images are renders that show the intended finishes (silver and gunmetal with gilt accents, jade, emerald and ruby stones, marble squares). The files are single-material print masters, ready to paint or plate. The finest details (lacing studs, bezels, crown feathers) need a high-resolution resin printer.
