Is the Toy castle 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: 1,608 triangles, 4,320 vertices and 35 materials, modelled in metres at 46 cm × 39 cm × 44 cm.

Can I animate Toy castle?

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 Toy castle 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.

Toy castle

A painted wooden toy castle on a baseboard: four crenellated white walls, blue corner towers with red cone roofs and yellow pennants, a tall yellow keep with a red flag, and an arched gate with a chained drawbridge lowered. Flat-shaded low-poly in the Toy Box kit palette.

How it was made

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

Toy castle 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 toy scale at default params: the baseboard is 0.46 m wide x 0.442 m deep, and the castle stands 0.386 m tall to the pennant tips, a floor toy a child can play with. Metres, +Y up, the gate faces +Z, origin at the bottom centre of the baseboard, which rests exactly on y = 0. Walls, towers and keep are seated 1 mm into the board, and the lowered drawbridge lies on it. 1608 triangles, no textures, no animation clip (static asset). Every material is named for the exact Toy Box palette colour it uses: 'wood' for the board top, 'dark wood' for the board edges, drawbridge, keep door and flagpoles, 'warm white' for the walls, 'blue' for the tower drums, 'blue dark' for the tower collars and keep cornice, 'yellow' for the keep and pennants, 'primary red' for the cone roofs and keep flag, and 'soot black' for the windows, arrow slits and chains. The kit recolours by name, and the role is stored on material.userData.role. The viewer's GLB exporter clones one material per mesh, so the file has 35 material records drawn from those 8 names, and merging by name is safe. toyEra changes shape only, never colour: 0 gives an older, squat block castle (low towers, shallow battlements, short cones, small flags) and 1 a taller fairy-tale castle (tall towers, deep battlements, steep spires, bigger flags). drawbridge swings the plank from closed in the gate (0) to lying on the baseboard (1). All params rebuild geometry. Part ids use the 'toycastle.' prefix because the kit's part-id grammar does not allow hyphens. Wall ends are deliberately buried inside the tower drums, and the windows and slits are thin plates a few millimetres proud of their faces. These designed joins trip glb-lint's sibling-overlap heuristic. glb-lint reports 0 errors and 5 warnings, all expected: material count and duplicate materials (both from the per-mesh clones), non-indexed merged geometry (flat shading), sibling overlap (the designed joins) and scale (0.39 m is set against a generic 1 m reference height). Its overall verdict reads UNVERIFIED only because no requirements contract was supplied. The ground disc and lights are viewer staging and sit outside exportGLB({scope:'model'}).
