About this model
Build it with one to six blades, two to a floor, back to back around a central chimney, with the desktop drawer in the base: one or two blades make a single floor, five or six make three, up to 2.4 m. Open colonnades on every storey, a gallery of 16 arches between the floors and a belfry on top. It stays upright with any one blade pulled out, at every size.
Worth knowing
The heaviest model here, and the priciest to print. From the front you see the boards rather than the arches; it reads clearest in white.

Budget black PETG.
Drives: every board keeps the drive its laptop came with (system only), so there is nothing to buy. A board bought without one needs a 256 GB M.2 2280 drive (approx. €56). Optional, not in the total: one shared disk of 1 TB or more for the render manager's shared folder, on the desktop board in the drawer, in its M.2 slot. Reuse an old one, or buy a 1 TB M.2 2280 drive for approx. €136–146. Drive prices are approximate (October 2026): check before buying.

To print it at this size: 15.3 kg of PETG. Add 10% for waste and test pieces and that is 17 spools of 1 kg, approx. €238–323 with the PETG below (the shopping list above already includes filament). Print time, estimated: about 827 h with the standard 0.4 mm nozzle (Ender-3 V3 SE class), 514 h with a 0.6 mm nozzle.
Print times are slicer estimates (OrcaSlicer) and may vary by ±15 %.
