Is the Block towers 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), 46 KB: 276 triangles, 571 vertices and 19 materials, modelled in metres at 36 cm × 28 cm × 28 cm.

Can I animate Block towers?

It ships as a static mesh. Its 20 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 Block towers 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.

Block towers

A child's cluster of stacked wooden toy blocks: a tall striped tower with a red triangle roof, a column tower with a cone cap, a two-pillar gate with a plank lintel and two loose blocks on the floor. Low-poly, flat-shaded, at real toy scale.

How it was made

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

Block towers 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 0.36 m wide x 0.285 m tall x 0.275 m deep (5 cm unit blocks); origin at bottom centre, front faces +Z, every block rests face-to-face on the one below or on y = 0 (the gate peak is embedded 0.4 mm into the lintel). Static asset, no animation clip. Materials are named exactly after Toy Box palette colours; the exporter writes one material copy per mesh, so several materials share a name (e.g. five 'blue'), which recolours together by name. Toy era swaps colours within the palette: below 0.33 vintage (primary red dark, blue dark, warm white, wood), 0.33-0.66 classic primaries plus wood (the shipped GLB), above 0.66 modern tints (primary red light, blue light, yellow, warm white). Group nodes carry the toy-box-kit-block-towers.* ids; block meshes carry blocktowers.* ids. glb-lint has no blocking errors; its warnings are the duplicate-name materials above and a scale heuristic expecting ~1 m (the asset is deliberately toy-sized). The viewer's ground disc and lights are not in the GLB.

About the Block towers 3D model
