Is the Building bricks 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), 163 KB: 2,236 triangles, 6,708 vertices and 5 materials, modelled in metres at 11 cm × 8 cm × 8 cm.

Can I animate Building bricks?

It ships as a static mesh. Its 6 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 Building bricks 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.

Building bricks

A stepped stack of four chunky toddler-size interlocking bricks (red, blue, yellow and light red) with round studs, plus a loose white brick tipped on its side to show its hollow underside and tube.

How it was made

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

Building bricks 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 0.113 m wide x 0.080 m tall x 0.079 m deep (16 mm stud pitch, toddler-brick scale); origin at bottom centre, front faces +Z. Each brick is a single flat-shaded mesh (hollow shell, top plate, 12-sided studs, underside tubes), and each material is named exactly after its Toy Box palette colour. Toy era swaps colours within the kit palette: below 0.33 is vintage (primary red dark, blue dark, wood, dark wood, and the bricks have no tubes), 0.33-0.66 is classic primaries (the shipped GLB), and above 0.66 is modern light tints. Static asset with no animation clip. glb-lint reported 0 errors and 3 heuristic warnings, all expected: the primitives are non-indexed on purpose so the flat normals survive, the asset is small because it is real toy scale, and the stacked bricks are flagged as 'detached' because their studs sit tangent inside the tubes of the brick above without any intersecting geometry. The wooden floor disc in the preview is viewer staging only and is not in the GLB.
