Is the Propellers 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), 88 KB: 688 triangles, 2,064 vertices and 27 materials, modelled in metres at 95 cm × 2.0 m × 95 cm.

Can I animate Propellers?

It ships as a static mesh. Its 6 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 Propellers 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.

Propellers

A low-poly light-aircraft propeller on a ground-crew prop stand: two twisted, tapered timber blades with orange-painted tips round a bolted hub, carried at engine height on a steel post with cross feet.

How it was made

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

Propellers for the Airfield 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 Airfield kit (Low-poly style, flat-lowpoly direction): Small planes on a grass strip. Use ONLY the kit palette, by name: grass green #3a883a, hangar white #f4f1ec, signal orange #ff851a, sky blue #2e67b8, grass green dark #235223, hangar white dark #d7cebc, grass green light #5db15d, hangar white light #f9f8f6, 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: about 0.95 m wide × 0.95 m deep × 1.97 m tall at default params. The prop is 1.85 m in diameter, a typical light-aircraft prop, and its axle sits 1.13 m up on the stand, so the tips clear the grass by 0.2 m. The blades are set 62° from horizontal, which is why the footprint is narrower than the prop. The origin is at the bottom centre on y = 0, and the prop's front (nose nut or spinner) faces +Z. The GLB has 688 triangles in 27 meshes, is static and carries no animation clip. Normals are baked flat (non-indexed geometry). Every material is named exactly after a kit palette colour, and 4 of the 12 colours are used at the default era. The exporter writes one material per mesh, so a colour name appears on several materials: recolour by name. era (the kit's 'Era') follows the Airfield hangar's split. Below 0.6 (the default 0.5) you get a laminated timber prop with a bolted hub plate. From 0.6 up you get slimmer mid-grey aluminium blades with a faceted hangar-white spinner. diameter, bladeCount (2–4) and pitch (the blade twist) rebuild the prop, and the stand height follows the diameter. The GLB is baked at default params, so the params only change geometry when the scene is rebuilt in the viewer. The extreme case (era 1, 2.2 m, 4 blades, 35° pitch) was also built: three-check passed and glb-lint reported 0 errors. glb-lint: 0 errors and 4 warnings, all expected: material count, duplicate-named materials, non-indexed primitives, and the painted tips flagged as 'detached' (each tip shares its seam face with its blade). Its verdict reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects the hyphens in the slug-based part ids this library requires; the same plan with the slug de-hyphenated passes. three-check, run with the real hyphenated ids, passes all 24 checks. The fix round widened the view margins so the blade tips and stand feet are no longer cropped, and moved the 4-blade phase so no blade hides the post.

About the Propellers 3D model
