Is the Skeleton 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), 353 KB: 4,670 triangles, 17,886 vertices and 21 materials, modelled in metres at 3.6 m × 1.8 m × 96 cm.

Can I animate Skeleton?

It ships as a static mesh. Its 15 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 Skeleton 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.

Skeleton

A low-poly mounted dinosaur skeleton for a natural history hall. It has an open-jawed skull with teeth, a rib cage, a long tail and striding three-toed legs, held up by brass rods on a dark wood plinth with a blank brass label plate.

How it was made

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

Skeleton for the Museum 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 Museum kit (Low-poly style, flat-lowpoly direction): Quiet halls of old things. Use ONLY the kit palette, by name: marble white #f4f1ec, deep red #861313, brass #b28c34, slate #525e6f, marble white dark #d7cebc, deep red dark #430a0a, marble white light #f9f8f6, deep red light #c32222, 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 `collectionTheme` (0–1, default 0.5) for the kit's "Collection theme" setting wherever it makes sense on this part, and keep that id.

Note: Size: the whole mount is 3.58 m long, 0.96 m deep and 1.78 m tall. The skeleton itself is a mid-sized theropod, 3.5 m from snout to tail tip, with the hips 1.22 m above the floor. It stands on a 2.2 m × 0.9 m plinth that is 0.22 m tall. The display front (the broadside and the label plate) faces +Z, and the skull points +X. The origin is at the bottom centre and the plinth rests on y = 0. The GLB has 4,670 triangles and no animation. Every material is named exactly after a kit palette colour: mid grey bones, soot black teeth, claws and plinth toe, dark wood plinth and brass rods and plate at the default theme. The runtime's exporter writes one material per mesh, so the same colour name appears on several materials (21 in total, 4 distinct colours). Recolour by name. Geometry is non-indexed with face normals, so it stays faceted in every engine. The label plate is blank brass with no text. Bones overlap their neighbours at the joints. The jaw hinge sits inside the skull, the toes sink 3 mm into the plinth top, the brass rods enter the vertebrae they carry, and the plate sits 2 mm into the plinth front. These overlaps are deliberate. Params are baked at their defaults and only change the model when the scene is rebuilt in the viewer. neckRaise lifts the neck from a low stalking pose to a raised alert one. tailSweep curves the tail sideways towards +Z, by up to 0.6 m at the tip. The minimum jawOpen of 6° keeps the teeth clear of the skull. collectionTheme (the kit's 'Collection theme') picks the finish: below 0.33 is aged bone (marble white dark) on a slate plinth, 0.33–0.67 (default) is a grey fossil cast on dark wood, and above 0.67 is a warm white cast on a deep red dark plinth. Both param extremes were rendered and checked (neck, tail, jaw and theme at their minimum and maximum values), along with the defaults. glb-lint reports 0 errors and 5 warnings: material count and duplicate materials (both from the per-mesh clones), non-indexed geometry (deliberate flat shading), the rod bounding box overlapping the pelvis (the rods are long and thin), and the jaw and plate flagged as detached (each is a child node embedded in its parent). Its verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphen in the slug-based ids this library requires; with the ids substituted it passes. three-check accepts the real ids, and all 15 survive the GLB reload.

About the Skeleton 3D model

Skeleton is a free low-poly 3D model from the Museum set. It measures 3.6 m × 1.8 m × 96 cm (W × H × D) at real-world scale and is built from 4,670 triangles across 21 meshes, with 15 named parts. Download the 353 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
