Is the Drums 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), 98 KB: 1,136 triangles, 3,408 vertices and 20 materials, modelled in metres at 1.5 m × 1.1 m × 1.0 m.

It ships as a static mesh. Its 13 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 Drums 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.

Drums

A low-poly pair of Aztec temple drums on a stone dais: a tall three-footed huehuetl with a spotted skin head, red lacing band and carved jade panels, and a horizontal teponaztli slit drum on stone cradles with two rubber-headed mallets.

How it was made

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

Drums for the Aztec Temple 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 Aztec Temple City kit (Low-poly style, flat-lowpoly direction): A city on a lake with stepped pyramids. Use ONLY the kit palette, by name: stone grey #757e8a, turquoise #31c4b8, feather red #c32222, jade #389475, stone grey dark #525860, turquoise dark #22877e, stone grey light #a3a5a8, turquoise light #6dd5cc, 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 `carvingColour` (0–1, default 0.5) for the kit's "Carving colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: 1.50 m wide × 1.00 m deep × 1.12 m tall. The stone dais is 0.11 m high; the huehuetl stands 1.0 m on it and is 0.48 m across; the teponaztli slit drum is 0.62 m long. The bottom rests on y = 0, the origin is at the bottom centre and the front (+Z) faces the slit drum and mallets. The GLB has 1,136 triangles in 20 meshes, is static and has no animation clip. Every material is named exactly after a kit palette colour (9 of the 12; turquoise dark, turquoise light and mid grey are unused). The exporter writes one material per mesh, so some names repeat: recolour by name. carvingColour (the kit "Carving colour" setting) picks the colour of the huehuetl's carved panels and the slit drum's end caps in five steps: stone grey light, turquoise, jade (default), feather red, warm white. drumHeight, drumDiameter and slitDrumLength reshape the drums; the params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. Only the defaults were rendered and checked. glb-lint: 0 errors, with 5 expected warnings (per-mesh materials over the direction default of 10 though only 9 distinct names; duplicate per-mesh materials; non-indexed flat-shaded geometry; nested parts such as panels on the body; and a bounding-box 'detached' heuristic for the lacing and log, which visually sit on the body and in the cradles). Its overall verdict is UNVERIFIED only because no requirements contract was supplied. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen; the same plan with the slug de-hyphenated passes. three-check and the GLB reload keep all ids. The ground disc in the preview is viewer staging and is not in the GLB.
