Is the Fuel rigs 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), 166 KB: 1,940 triangles, 5,820 vertices and 35 materials, modelled in metres at 2.4 m × 3.1 m × 2.3 m.

Can I animate Fuel rigs?

It ships as a static mesh. Its 9 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 Fuel rigs 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.

Fuel rigs

A low-poly pit-lane refuelling rig on a skid: a tall banded fuel tank with a sight gauge, a pump cabinet with its control panel, and a mast and boom carrying the fuel and vent hoses out to a hanging refuelling nozzle.

How it was made

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

Fuel rigs for the Racing Circuit 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 Racing Circuit kit (Low-poly style, flat-lowpoly direction): Speed, pit stops and crowds. Use ONLY the kit palette, by name: tarmac #34373d, kerb red and white #f4f1ec, flag colours #988e81, grass #539b3b, tarmac dark #101113, kerb red and white dark #d7cebc, tarmac light #5c5d61, kerb red and white light #f9f8f6, 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 `teamLiveries` (0–1, default 0.5) for the kit's "Team liveries" setting wherever it makes sense on this part, and keep that id.

Note: Size at default params: about 2.4 m wide (X) × 2.6 m deep (Z, including the boom reaching out over the pit lane) × 3.14 m tall to the boom top. The skid is 2.4 × 1.6 m and the tank is 1.24 m across. Origin at the bottom centre of the bounding box, resting on y = 0 on two timber runners. The pit-lane side faces +Z. Static: no animation clip. The GLB is baked at the default params: 1,940 triangles, 35 meshes, one per part and palette colour. Every material is named after its kit palette colour so the kit recolours by name; names repeat because the exporter writes one material per mesh. Team liveries (the kit knob) is the share of four livery slots painted in flag colours instead of plain kerb tones: three tank wrap bands and the cabinet door, centre band first. At 0.5, the centre band and the door are liveried. Tank height, boom reach and hose count rebuild the model in the viewer only; the GLB is the default build. glb-lint: 0 errors and 6 expected heuristic warnings: duplicate palette materials per mesh, the material count, non-indexed flat-shaded geometry, nested trim counted as overlaps, the feed pipe and the hanging nozzle counted as 'detached', and a height above the direction's 1 m reference. The kit's plan-check rejects the hyphenated library part ids, because its regex allows no hyphen in the first segment; a de-hyphenated copy of the plan passes.
