Is the Marbles 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), 178 KB: 1,796 triangles, 7,228 vertices and 26 materials, modelled in metres at 18 cm × 7 cm × 16 cm.

Can I animate Marbles?

It ships as a static mesh. Its 16 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 Marbles 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.

Marbles

A blue cloth drawstring pouch tipped on its side, with eight swirl marbles and one big red shooter rolled out of its mouth. Low-poly toy for a child's floor scene.

How it was made

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

Marbles for the Toy Box 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 Toy Box kit (Low-poly style, flat-lowpoly direction): A child's floor seen from toy height. Use ONLY the kit palette, by name: primary red #c32222, blue #2e67b8, yellow #eecd2b, wood #7d5736, primary red dark #821717, blue dark #1f457a, primary red light #db5757, blue light #6190d1, 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 `toyEra` (0–1, default 0.5) for the kit's "Toy era" setting wherever it makes sense on this part, and keep that id.

Note: Real-world size: about 0.18 m wide x 0.155 m deep x 0.071 m tall as a set. Standard marbles are 16 mm across, the shooter 25 mm, and the pouch about 11 cm long. Origin is at the bottom centre of the whole set. Materials are named by their exact Toy Box palette colour (for example 'blue' or 'warm white') so the kit can recolour them, and they carry the palette name, not a body/trim role. The marbles are opaque flat-shaded swirl marbles, not glass. Toy era (0 = vintage, slightly lumpy marbles with a wide swirl in a long crumpled sack; 1 = modern round marbles with a crisp band in a neater pouch) changes only geometry, never colour. The GLB ships with the default 8 marbles; marbleCount, shooterSize and pouchLength only take effect when the scene is rebuilt in the viewer. 'primary red dark' only appears when there are 10 or more marbles. The exporter writes one material copy per mesh, so the same palette name appears several times in the GLB (26 entries, 9 unique colours). glb-lint gives no errors, only advisory warnings for the duplicate materials and the small-object scale. Static model, no animation clip. 1796 triangles.
