Is the Drill tower 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), 450 KB: 6,044 triangles, 18,132 vertices and 30 materials, modelled in metres at 7.7 m × 17 m × 8.6 m.

Can I animate Drill tower?

It ships as a static mesh. Its 9 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 Drill tower 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.

Drill tower

A low-poly five-storey brick fire-service drill tower with open drill windows, scorched lintels and plank shutters. A red switchback fire escape climbs one side, a standpipe and rung ladder run up the other, a rope davit hangs off the roof, and a red extension ladder leans against a front window.

How it was made

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

Drill tower for the Fire Station 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 Fire Station kit (Low-poly style, flat-lowpoly direction): Ready for the alarm. Use ONLY the kit palette, by name: engine red #c32222, brick #9e3d2e, brass #b28c34, white #f4f1ec, engine red dark #821717, brick dark #63261d, engine red light #db5757, brick light #c66253, 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 `engineLivery` (0–1, default 0.5) for the kit's "Engine livery" setting wherever it makes sense on this part, and keep that id.

Note: Size at default params: about 7.5 m wide (x, including the 2 m fire escape on the right and the rung ladder on the left), 8.6 m deep (z, including the extension ladder's foot 3 m in front of the tower) and 17.1 m tall to the top of the davit. The brick shaft is 5 m square with 3 m storeys and a 1 m parapet, so the roof deck is at 15 m. The drill face (front windows and ground-floor double door) faces +Z, the origin is at the bottom centre of the footprint and the model rests on y = 0. The GLB has 6,044 triangles in 30 meshes (merged per part and colour) and no animation clip. With 6 storeys it is about 7,250 triangles, with 3 storeys about 3,900. Normals are baked flat (non-indexed), so the facets survive in any engine. Every material is named exactly after its kit palette colour, and all 12 kit colours are used at the default livery. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. engineLivery (the kit's 'Engine livery') repaints the fire-escape steelwork and the extension ladder in three bands: below 0.33 white steel with grey treads and red ladder tips; 0.33–0.67 engine red steel with engine-red-dark treads and white tips (default); above 0.67 engine red dark steel with soot-black treads and brass tips. floors sets the storey count (3–6), and the fire escape, standpipe and rung ladder follow it. ladderFloor picks which storey's right-hand front opening the ladder is pitched to, at 75°, and is clamped to the top storey. shutterOpen swings the side and back shutters from closed to nearly flat against the wall. The drill openings are dark voids, not modelled rooms. The model has no text or numbers. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. glb-lint: 0 errors; its heuristic warnings (duplicate materials from the per-mesh export, unindexed flat-shaded geometry, sibling overlap from trims embedded in walls, scale against the direction's 1 m reference) are expected. plan-check passes except for its part-id regex, which rejects the hyphens this library's slug-based ids need. The same plan with the slug de-hyphenated passes, and three-check finds all 9 ids in the scene and after the GLB reload.
