About this model

A neoclassical city gate with Doric columns, a two-step attic and a crown block over the middle. Each laptop blade stands inside its own pier, a box of lattice tiles with a column in front of each end, so from outside you see lattice piers and only a dark shadow of the board. Between the piers are empty passages you can look straight through, and the middle one is half as wide again, as on the real gates. You pick 2 or 4 computers: with four you get six piers, six columns on each side and five passages, 1.38 m long, and the gate is always 0.86 m tall. Air comes in low through the passages and the bottom of each pier, rises past the board and leaves through the attic and the lid. One 260 W supply runs them all; the supply, the network switch and the shared disk lie inside the plinth. To swap a blade you lift the lid above its pier and pull the blade straight up by its tab.

Worth knowing

This is the longest and heaviest compact model: 1.38 m and about 23.8 kg of filament with four computers (0.91 m and 15.6 kg with two), so measure the shelf and the print time first (about 950 hours on a fast printer with four). For the middle blades you lift the crown block off before the lid. The columns and piers carry the top; the blades only stand in their shoes.

Prices with VAT as shown in October 2026. Shipping, glue and the boards are not included. Also not counted, if you do not own them: a multimeter (about €8.56) and a power strip (about €15.12).

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 one laptop board, in its own M.2 slot, or in a USB case (approx. €19) on the base floor. 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.

No printer yet?

To print it at this size: 23.8 kg of PETG. Add 10% for waste and test pieces and that is 27 spools of 1 kg, approx. €378–513 with the PETG below (the shopping list above already includes filament). Print time, estimated: about 1,230 h with the standard 0.4 mm nozzle (Ender-3 V3 SE class), 783 h with a 0.6 mm nozzle.

Print times are slicer estimates (OrcaSlicer) and may vary by ±15 %.
