Print plans for a home render farm
Your old laptops, standing inside a pagoda, rendering your films.
Print the landmark, slide a laptop board into each blade, plug it in. Full-size builds from 1.21 to 1.88 m at their standard size, and a compact line that stays under 1 m.
Designed and checked in CAD. Not built in real life yet.

How it works
From a drawer of dead laptops to a render farm
An old laptop
A laptop with a cracked screen usually still has a working board. Take the board out; screen, keyboard and case stay behind.
A blade
The board goes into a printed blade: a slim lattice cassette with its own fan on top, and a fuse and a network socket in the foot.
A landmark
The blade slides into the tower and plugs itself in, power and network meeting at the bottom of the slot. One 260 W supply feeds them all.
A render farm
Each board is an ordinary computer on your network, so the network render tool you already use can send it frames. Our own software for this is not built yet.
The line-up
Landmarks that render
Two lines. The big models are landmark-size: laptop blades, plus a drawer for one desktop board, Mini-ITX up to ATX. The compact line stays under 1 m: up to 4 laptop boards packed inside, or up to 8 in a row in the temple, and no desktop drawer.

Decor
Your rack already hums like a city. Now it looks like one.
Printable decor for the servers you already own: a skyline for a 10-inch rack, a lantern for a mini PC, a city block for the desk. No boards to fit, no build, one USB light string.
Custom model
Your building isn't in the line-up? Send it to us.
A town hall, a church tower, a shape you drew yourself. We design it on the same laptop blades as the models above and reply by email.
What it costs to build
The plan is the small part of the bill
Parts and filament for each model at its standard size, then a used laptop for every blade. A broken laptop with a working board goes for about €40–60.

Prices with VAT from Amazon.de, Reichelt and DigiKey as shown in October 2026. Shipping, glue and the boards are not included.
The desktop drawer is optional: a used desktop board with CPU runs about €130–190, plus €91 for its DC-DC power board.
No printer yet?
Buy the printer. It costs less than having the parts printed.
For a model of about 12 kg, the cheapest print service we found with a published price would charge approx. €1,280 (read 18 Oct 2026). A printer and all the filament come to approx. €330–770, and you keep the printer.

Every printed part fits a 220 × 220 mm bed, so all three printers take them. The Bambu A1 mini (180 mm) is too small. Prices are from each shop's own page; shipping and the final VAT are added at checkout.
Before you ask
What is tested, and what isn't yet
Has this been built?
Not in real life yet. Every part is designed and checked in CAD: the fit of the boards, stability with blades pulled out, the power budget, and that each piece fits a 220 mm print bed. The print times come from the slicer. Nobody has printed or built a model so far, and we are not promising a date for the first build. Start with the free test coupon to check the fits on your printer. If something is wrong, tell us: we fix the files, and every buyer gets the updated files free.
Which laptops fit?
Boards from most 13 to 17 inch laptops: up to 280 × 390 mm, with nothing taller than 24 mm above the board. Big 18-inch gaming laptops are not guaranteed.
Won't it overheat?
The cooling is sized for laptop chips running at 15–25 W, with a fan in the head of every blade. Stronger boards should be capped at 25 W. On the big models the desktop drawer takes a CPU up to 65 W, without a tower cooler. These are design estimates; nothing has been measured on a real build yet.
What printer do I need?
Any printer with a bed of 220 mm or more, printing PETG. Every part is cut to fit that bed. Expect hundreds of print hours; each model page gives the range.
Do I need to buy drives?
Usually not. Every board keeps the drive its laptop came with and boots its system from it. Each model needs one shared disk of 1 TB or more, where the render manager (Flamenco) keeps the scenes and the finished frames, so your own computer stays free. An old 1 TB drive will do; a new one is about €136–146 (October 2026, check before buying). It sits on the desktop board in the drawer, or on one laptop board in the compact models.
What do I get when I buy?
The plan for one model, at every computer count it supports, so growing from two laptops to four costs nothing extra. Single models are €19, €24 or €29, VAT included. A free test piece lets you check your printer first.
How do I buy?
Open a model or a decor piece and press "Buy the plan". You tick one box about the download first, then you pay in the Lemon Squeezy checkout.
