Is the Signs 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), 216 KB: 2,180 triangles, 6,540 vertices and 11 materials, modelled in metres at 1.5 m × 2.6 m × 50 cm.

It ships as a static mesh. Its 6 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 Signs 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.

Signs

A low-poly cycle-route signpost: a white post on a grey footing with a round green bike-path disc on top and two red-edged cream finger boards pointing the bike routes left and right. Part of the Bicycle City kit.

How it was made

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

Signs for the Bicycle City 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 Bicycle City kit (Low-poly style, flat-lowpoly direction): Streets made for bikes. Use ONLY the kit palette, by name: brick red lanes #c32222, canal green #3a883a, bright bike colours #b39d80, cream #f1e7d0, brick red lanes dark #821717, canal green dark #235223, brick red lanes light #db5757, canal green light #5db15d, 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 `bikeColours` (0–1, default 0.5) for the kit's "Bike colours" setting wherever it makes sense on this part, and keep that id.

Signpost
Footing and base sleeve

Finial cap
Cycle-path disc
Route finger boards

Note: Size at the defaults: about 1.54 m wide (x, tip to tip of the finger boards) × 0.5 m deep (z, the footing) × 2.63 m tall to the finial tip. The disc is 0.56 m across and the boards are 0.17 m tall. Origin is the bottom centre of the footing on y = 0, the disc faces +Z, and the fingers point ±X. The boards carry a bicycle pictogram on both faces and the disc has a grey back plate, so every side looks finished. The sign has no lettering, numbers or logos. The GLB has 2,180 triangles in 11 meshes, one mesh per part and colour. Normals are baked flat (non-indexed). It is static and carries no animation clip. Every material is named exactly after its kit palette colour, and 7 of the 12 kit colours appear at the defaults. bikeColours (the kit's 'Bike colours') sets how loud the sign reads: below 0.25 it uses canal green dark and brick red lanes dark, up to 0.75 canal green and brick red lanes, and above 0.75 canal green light and brick red lanes light. postHeight, fingerCount (1–4, alternating right/left) and fingerLength change the geometry. All params are baked into the GLB at their defaults and only take effect when the scene is rebuilt in the viewer. Only the default build was rendered and checked; the param extremes were not. glb-lint: 0 errors. Its verdict reads UNVERIFIED only because no requirements contract was supplied. The 6 warnings are heuristics: duplicate material names, non-indexed flat shading, nested layer boxes, 'detached' post and cap (both are embedded in the sleeve and post), and a height above the 1 m reference. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen; the same plan passes with the slug de-hyphenated. three-check and the GLB keep all 6 ids. One fix round, visual only: full-height black finger collars replaced with thin clamp bands, and the board bicycles centred on their fields.

About the Signs 3D model

Signs is a free low-poly 3D model from the Bicycle City set. It measures 1.5 m × 2.6 m × 50 cm (W × H × D) at real-world scale and is built from 2,180 triangles across 11 meshes, with 6 named parts. Download the 216 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
