CUBEUNi designs 3D-printed trains, stations, bridges and track accessories for wooden train sets — every part comes off your own 3D printer, modelled on a real vehicle and sized to fit BRIO and IKEA LILLABO track. Download the files on MakerWorld, print them at home, and they run and couple with the trains already in your toy box.
All models live on MakerWorld — free to download there.
Commercial licences are handled on MakerWorld too.
Every design leaves the printer as a finished toy — it clips together without tools, drops straight onto the wooden track, and links up with the trains already in the toy box.

Ranked by print count — how many times each model has actually been printed by the people who downloaded it.
The most-printed pieces here aren't the flagship trains — they're the little functional parts: a track switch, a car wash, a container garage, a buffer stop. Each one prints in a single sitting and drops straight onto the track you already own. Want something running tonight? Start here.
Rolling stock, stations, bridges, track, scenery and motorised kits — everything here is built for the same wooden track and the same magnet couplers. Filter by family, or search for a vehicle. Every card opens its listing on MakerWorld, where the files are free to download.

| Coupling | Ø8 × 3 mm disc magnets, 2 pockets per car, N/S oriented, press-fit |
| Hardware | Ø8 mm disc magnets; some kits also use M3 screws — every listing carries its own BOM |
| Assembly | Clip-fit on most models. No glue, no tools |
| Tested on | Bambu Lab A1 mini · 0.4 mm nozzle |
| Print settings | 0.2 mm layers · 3 walls · 15% infill · PLA |
| Supports / AMS | None required on most models — each listing states it explicitly |
| Where to get them | Every model is published on MakerWorld, free to download and print |
Same models, two very different situations. The line between them is simple: printing for yourself is free, selling prints needs a licence.
Download, print, run. That's the whole workflow.
Selling physical prints of these designs requires a commercial licence. Two ways to get one:
If your track is BRIO, IKEA LILLABO, or any other brand using the same gauge, yes. Coupling is by Ø8 × 3 mm disc magnets in N/S orientation, so cars link in either direction and mix freely with the trains you already own.
Most models are designed to print without either, and every listing states explicitly what it needs. If a model does need supports, it's written on the listing rather than left for you to discover.
Yes — with a commercial licence. The fastest way is to buy it directly on MakerWorld from the designer profile. For business enquiries, bulk licensing or custom vehicle work, email superwen1986@hotmail.com.
Bambu Lab A1 mini with a 0.4 mm nozzle — 0.2 mm layers, 3 walls, 15% infill. Anything that fits on an A1 mini will also print on a larger machine.
Yes. Print in whatever filament you have, or scale the parts up or down. Just remember that scaling changes the coupler height, so check the magnet pockets still line up with your track's other cars before printing a whole rake.
Model names describe the vehicle type rather than the operator, and brand names only ever appear in the form "compatible with". It keeps the library tidy to search, and it keeps every listing on the safe side of the platform's rules.
Everything is published on MakerWorld — that's where the files live and where new models appear first. Follow the account there and you'll see new releases as they land.
Most models here started as somebody's request. Missing a vehicle — or does the person with the crayons have opinions? Send it over.
A three-year-old's crayon train is a perfectly good brief.
Ideas go straight to me superwen1986@hotmail.com No form, no account — think it, send it.
New rolling stock and scenery get published regularly. If there's a particular train you'd like to see on the track, send a message — requests usually go to the front of the queue.
