Is the Trapeze 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), 164 KB: 1,524 triangles, 6,628 vertices and 17 materials, modelled in metres at 2.5 m × 3.2 m × 1.8 m.

Can I animate Trapeze?

It ships as a static mesh. Its 19 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 Trapeze 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.

Trapeze

A low-poly freestanding circus practice trapeze. Two candy-striped posts on dark-wood skids hold a gold crossbeam, and a black trapeze bar hangs at rest on two white ropes above a midnight-blue safety mat.

How it was made

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

Trapeze 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 at default params: 2.54 m wide (the crossbeam overhangs the posts), 3.19 m tall (top of the finial balls; the top of the crossbeam is at 3.0 m) and 1.8 m deep (skid length). The posts stand 2.2 m apart. The bar is 0.8 m between the ropes and hangs 1.6 m above the floor. The origin is at the bottom centre, the model rests on y = 0, and the open front faces +Z. The GLB has 1,524 triangles in 15 meshes. It is static and has no animation clip. stripeColours (the kit's 'Stripe colours') picks the colour that alternates with 'red and white stripes' on the posts: gold below 0.33, midnight blue from 0.33 to 0.67 (the default), and 'red and white stripes dark' above 0.67. That last option is a deliberately quiet cream-on-white. Every material is named exactly after a Circus kit palette colour; 9 of the 11 are used at the defaults, and 'red and white stripes light' is not used. The exporter writes one material per mesh, so names repeat: recolour by name. Matching parts are merged into one mesh each (both ropes, all four pads, all braces), so they recolour together. The GLB is baked at default params; the params only change geometry when the scene is rebuilt in the viewer. barHeight is clamped so at least 0.75 m of rope stays above the bar, and the bar never drops below 0.7 m. Both extremes passed three-check: all-max (3.6 m frame, 2.8 m width, 2.2 m bar, 21 bands, stripes 1) and all-min (2.6 m, 1.8 m, 1.0 m, 5 bands, stripes 0). glb-lint gives 0 errors. Its warnings are expected heuristics: material count and duplicate names (one material per mesh), non-indexed geometry (flat facets), overlap where the posts deliberately sink into the skids and collars, and the 3.2 m height compared with the direction's 1 m reference. Its verdict reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects only the hyphen in the slug-based part ids this library requires, because its id regex allows no hyphen. The same plan with the slug de-hyphenated passes. Fix rounds: (1) reframed the hero, front and side views so the skids clear the frame and the toolbar; gave the mat a solid core so the seams between its panels no longer show the floor; thickened the bar and ropes. (2) Seated the finial balls on their necks (they had floated 3 mm) and tightened the portrait framing.
