About this model
A popcorn cart from no particular fair or maker, with no lettering on it: a red cabinet with bold yellow stripes on every side, a spoked wheel on each side and a push handle at the back. On top sits the glass case with a kettle hanging from the roof, heaped with popcorn, and more popcorn piled in its corners, under a flat canopy with a scalloped edge and a pointed crown. Up to four laptop blades stand in a row inside the cabinet. Its walls are solid, so from outside you never see a computer board; the stripes, wheels and handle are glued on. Air comes in through the slatted vents in the plinth and leaves through the open panes of the case. At night a strip under the canopy lights the kettle and the popcorn, and the case glows on all four sides. You pick 2, 3 or 4 computers and the model stays the same size: 0.60 x 0.54 m, 97 cm tall.
Worth knowing
About 10.7 kg of filament with two computers and 12.4 kg with four (roughly 360 to 420 hours on a fast printer), in two colours: red for the cabinet, the case, the canopy and the crown, and yellow for the stripes, wheels, handle, kettle and popcorn. There are many small glued parts: 72 stripes, set them on the wall with a spacer so the red gaps stay even. The wheels and the handle are decoration, do not push or lift the cart by them. The glass case has no glass, its panes are open for the air. The top (plate, case, canopy, crown, kettle and popcorn glued into one) is not glued down because it is the way in; lift it straight up with both hands by the plate, not by the canopy.

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.
