Is the Diner 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), 140 KB: 1,620 triangles, 4,860 vertices and 32 materials, modelled in metres at 15 m × 6.9 m × 11 m.

It ships as a static mesh. Its 8 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 Diner 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.

Diner

A low-poly classic roadside diner: a long chrome diner car with a ribbon of dark windows over a cherry red band, a faceted barrel roof and a cherry red sign raised on posts above it. A central entrance vestibule with steps and a canopy faces the road, and a kitchen annex with an exhaust stack sits at the back.

How it was made

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

Diner for the Roadside Diner 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 Roadside Diner kit (Low-poly style, flat-lowpoly direction): A lonely stop on a long road. Use ONLY the kit palette, by name: chrome #cad1d8, cherry red #c32222, mint #90d5b3, desert tan #bf9769, chrome dark #9eabb7, cherry red dark #821717, chrome light #f7f7f8, cherry red light #db5757, 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 `era` (0–1, default 0.5) for the kit's "Era" setting wherever it makes sense on this part, and keep that id.

Note: Size: the diner car is 15.0 m long (x) and 5.2 m deep (z), sitting on a 0.5 m plinth with its eaves at 3.4 m and the barrel roof crown at 4.1 m. The roof sign tops out at 6.92 m. With the entrance vestibule and steps at the front and the kitchen annex at the back, the whole footprint is about 15.3 m by 10.6 m. The entrance faces +Z, and the origin is at the bottom centre of that footprint, resting on y = 0. The exported model has 1,620 triangles in 32 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed). All 12 kit colours are used, and every material is named exactly after its palette colour. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. The sign carries abstract colour blocks, never real text. The windows are opaque dark glass with no interior behind them. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. era (the kit's 'Era') runs from a 1940s car (barrel roof 1.0 m high, four skirting flutes, a short flat canopy) to a 1960s one (0.4 m roof, two flutes, a 1.8 m canopy swept up about 12°). length sets the car's length and its window count, plus the sign width. signHeight lifts the sign on its posts. The param extremes were checked by reading the geometry limits, not by a capture. glb-lint: 0 errors and 6 heuristic warnings: material count and duplicate materials (from the per-mesh materials), unindexed geometry (flat shading on purpose), sibling overlap (bands and trims embedded on purpose), a 'detached' windows mesh (the panes are embedded 2 cm into the body) and scale (compared with the direction's 1 m reference). 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. three-check accepts those ids, and all 8 survive the GLB reload.

About the Diner 3D model

Diner is a free low-poly 3D model from the Roadside Diner set. It measures 15 m × 6.9 m × 11 m (W × H × D) at real-world scale and is built from 1,620 triangles across 32 meshes, with 8 named parts.
