Is the Vault 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), 153 KB: 1,816 triangles, 10,932 vertices and 23 materials, modelled in metres at 2.8 m × 2.7 m × 4.1 m.

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 Vault 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.

Vault

A low-poly walk-in museum strongroom: a marble-clad block on a slate plinth with a hipped slate roof and a thick steel door on brass hinges. The door stands open over a stone landing, showing a red-lined interior with shelves of collection boxes and urns.

How it was made

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

Vault 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 overall footprint is 2.76 m wide by 4.10 m deep, and the vault is 2.70 m tall to the roof peak. The vault block is 2.60 x 2.60 m and sits on a 2.76 x 2.76 m slate plinth (0.16 m high). In front is a 2.04 m wide stone landing, so the open door swings over stone instead of hanging in the air. The door opening is 1.12 x 2.05 m. The door is 0.24 m thick and hinged on the front-left edge of the opening. The origin is at the bottom centre of the whole footprint (plinth plus landing), and the plinth rests flat on y = 0. The front faces +Z. The GLB has 1,816 triangles and 16 named parts, and it carries no animation. It is a static piece. doorOpen sets the door angle when the model is built (0 is shut, 1 is 105 degrees, default about 79 degrees). Every material is named exactly after a kit palette colour (9 distinct names at the default theme). The exporter clones materials per mesh, so the same name repeats (23 material slots). Recolour by name. Faces are flat-shaded (non-indexed geometry with face normals). The name plate and dial are blank brass, with no text. Part ids drop the hyphen (museumvault.*) because the kit's plan-check id rule rejects hyphens. collectionTheme (the kit's 'Collection theme') sets the finish and what the vault holds. Below 0.33 is an archive store: slate walls, a soot black lining and wooden crates. 0.33 to 0.67 (default) is a classical strongroom: marble cladding, a deep red lining, red cases, white boxes and brass urns. Above 0.67 is a modern store: black cladding, a deep red lining and pale boxes. The shelf contents are placed by a seeded generator (seed 7). Params are baked at their defaults and only change the model when the scene is rebuilt in the viewer. Only the default params were rendered and checked. glb-lint reports 0 errors and 5 warnings: material count and duplicates (both from the per-mesh clones), non-indexed geometry (deliberate flat shading), sibling bounding-box overlap (the walls, trim, frame and lining nest around the hollow interior), and height versus the direction's 1 m reference (the vault is really 2.7 m tall). Its verdict reads UNVERIFIED only because no host requirements contract was supplied. Overlaps are deliberate: hinge leaves touch the frame, locking bolts run into the jamb when the door is shut, and the threshold plate sits inside the frame.

About the Vault 3D model
