Is the Trolleys 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 85 KB: 880 triangles, 2,640 vertices and 26 materials, modelled in metres at 62 cm × 1.0 m × 1.0 m.

Can I animate Trolleys?

It ships as a static mesh. Its 11 named parts are separate nodes, so you can move or animate each one in your engine.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Trolleys 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Trolleys

A low-poly airport baggage trolley with a grey load deck, rubber strips and a kicked-up nose lip. A leaning back frame carries a navy livery board with a signal-yellow band, a fold-down hand-luggage tray and a push handle with a brake bar, on two fixed rear wheels and two front swivel casters.

How it was made

The brief given to 1DesignTool's “3D object” template:

Trolleys for the Airport Terminal kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. This is one part of the Airport Terminal kit (Low-poly style, flat-lowpoly direction): Check-in to gate. Use ONLY the kit palette, by name: cool grey #7c7e83, navy #1c2a54, signal yellow #ffdb29, white #f4f1ec, cool grey dark #57585c, navy dark #090d1b, cool grey light #a6a6a6, navy light #344989, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `airlineLivery` (0–1, default 0.5) for the kit's "Airline livery" setting wherever it makes sense on this part, and keep that id.

Note: Size: a standard airport baggage trolley, 1.04 m long overall, 0.62 m wide and 1.05 m to the top of the push handle. The load deck is 0.74 m long with its top 0.24 m off the ground. The rear wheels are 0.18 m across and the front casters 0.13 m. The origin is at the bottom centre with the wheels resting on y = 0. The nose faces +Z and the push handle is at -Z. The exported model has 880 triangles in 26 meshes. Every material is named exactly after a kit palette colour; 8 of the 12 are used (white, navy light, warm white and dark wood are not). The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. The model is static, with no animation clip. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. airlineLivery (the kit's 'Airline livery') sets how much of the navy board the yellow band covers, from 12% to 62%. deckLength stretches the deck, chassis and nose. handleHeight raises the push handle, back frame and board. trayOpen at 0 folds the hand-luggage tray up against the board. three-check passed at both extremes (livery 1, deck 0.60 m, handle 0.92 m, tray folded; livery 0, deck 0.90 m, handle 1.15 m, tray half open). glb-lint: 0 errors and 5 warnings. Two are about material count and duplicates, both caused by the per-mesh materials. One flags non-indexed geometry, which is deliberate flat shading. One flags sibling overlaps where the axle, deck strips and livery band are deliberately nested. One flags parts that only touch other parts, such as the frame and caster plates seated on the chassis. Its verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. With the ids substituted it passes; three-check accepts the real ids and all 11 survive the GLB reload.
