Is the Ring 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), 143 KB: 1,664 triangles, 4,992 vertices and 16 materials, modelled in metres at 14 m × 1.4 m × 14 m.

It ships as a static mesh. Its 21 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 Ring 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.

Ring

A low-poly circus ring: a 13 m sawdust floor fenced by a striped ring curb with a gold rail. Two gold-topped gate posts flank the artists' entrance and a ringmaster's drum pedestal stands in the centre.

How it was made

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

Ring for the Circus 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 Circus kit (Low-poly style, flat-lowpoly direction): The big top comes to town. Use ONLY the kit palette, by name: red and white stripes #f4f1ec, gold #d0a225, midnight blue #123464, red and white stripes dark #d7cebc, gold dark #8f7019, red and white stripes light #f9f8f6, gold light #debd63, 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 `stripeColours` (0–1, default 0.5) for the kit's "Stripe colours" setting wherever it makes sense on this part, and keep that id.

Note: Size: the ring is 13.0 m across inside the curb (a standard circus ring) and 14.1 m across overall. The curb is 0.5 m wide and 0.45 m tall. The gate posts are 1.38 m tall to the top of the finials, which is the model's full height. Origin is at the centre of the ring floor and the model rests on y = 0. The front faces +Z and the entrance gap is at the back (−Z). The model has 1664 triangles in 16 meshes, with no textures and no animation clip. Each curb stripe is a single flat panel, so the stripes and the low-poly facets line up. stripeColours (the kit's 'Stripe colours') picks the stripe pairing in three steps: below 0.33 white and gold with a midnight-blue rail, 0.33–0.66 white and midnight blue with a gold rail (default), above 0.66 midnight blue and gold with a white rail. Material names stay palette names in every setting. On an open ring the stripe count is used as given; odd counts keep both gate ends the same colour. The front stripe is always centred and coloured. entranceWidth starts at 0.8 m so the gate posts and threshold, and their part ids, always exist. Params are baked into the GLB at their defaults and only change the geometry when the viewer rebuilds the scene. three-check also passes at both extremes. Every material is named after a Circus kit palette colour. The exporter writes one material per mesh, so names repeat; recolour by name. glb-lint reports 0 errors and 5 heuristic warnings, all expected. Material count and duplicates come from the per-mesh material copies. Geometry is non-indexed on purpose to keep facets flat. The overlaps are deliberately embedded joins: floor and track under the curb, threshold ends into the curb. The rail is flagged as 'detached' only because it sits half-sunk into the curb group rather than a sibling. plan-check rejects only the hyphenated 'circus-ring.*' part ids the library requires, because its regex allows no hyphen; the same plan with the slug de-hyphenated passes.

About the Ring 3D model

Ring is a free low-poly 3D model from the Circus set. It measures 14 m × 1.4 m × 14 m (W × H × D) at real-world scale and is built from 1,664 triangles across 16 meshes, with 21 named parts. Download the 143 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
