Is the Ladders 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), 81 KB: 972 triangles, 2,916 vertices and 14 materials, modelled in metres at 1.1 m × 2.4 m × 1.8 m.

Can I animate Ladders?

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 Ladders 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.

Ladders

A low-poly wooden tripod orchard picking ladder. Two tapering side rails carry seven flat treads, and a single pole leg is hinged under the top cap. A gold pail of red apples stands at its foot.

How it was made

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

Ladders for the Autumn Orchard 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 Autumn Orchard kit (Low-poly style, flat-lowpoly direction): Harvest time on a small farm. Use ONLY the kit palette, by name: russet #988e81, apple red #c32222, gold #d0a225, cream #f1e7d0, russet dark #70685c, apple red dark #821717, russet light #b6b3af, apple 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 `season` (0–1, default 0.5) for the kit's "Season" setting wherever it makes sense on this part, and keep that id.

Note: Size at the defaults: 1.07 m wide (x) × 2.40 m tall × 1.81 m deep (z), with the pole leg spread and the pail included. The ladder is a standard 8 ft (2.4 m) tripod orchard ladder. The rails splay from 0.76 m apart at the foot to 0.20 m under a 0.32 m top cap, the climbing face leans back about 11°, and the treads are about 0.29 m apart. The origin is at the bottom centre of the whole footprint (pail included), resting on y = 0. The climbing face points +Z and the pole leg reaches back toward −Z. The rail feet and the pole foot are cut flat on y = 0. The GLB has 972 triangles in 14 meshes and no animation clip. Normals are baked flat (non-indexed). Each material is named exactly after a kit palette colour. The exporter writes one material per mesh, so names repeat; recolour by name. season (the kit's 'Season', 0 = late summer, 1 = late autumn) shifts the apples in the pail from apple red light through apple red to apple red dark; it has no effect when pail = 0. height (1.8–3.0 m) rescales the rails and pole. treads sets 4–10 evenly spaced steps, with a tie rod under every other one. spread sets the pole leg angle (15–32°). pail = 0 removes the pail and apples, which leaves just the ladder (the pail and apples part ids then do not exist). Params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. Only the defaults were rendered and checked. glb-lint: 0 errors and 5 heuristic warnings, all expected: more than 10 materials and duplicate names (one material per mesh), non-indexed flat shading, nested sibling boxes (tie rods under treads, the bolt between the straps, the fill inside the pail), and height 2.4 m vs a 1 m reference (a real ladder is that tall). plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires; the same plan with the slug de-hyphenated passes. three-check accepts those ids, and all 8 survive the GLB reload. Fix round 1: rails and pole were thickened and darkened from russet to russet dark, and treads changed from russet light to russet, because the pale wood blended into the pale ground. The hero was also loosened (margin 1.0 to 1.12) because the front foot was cropped. Fix round 2: front and side were loosened (margin 0.95 to 1.06) because the pail was clipped at the bottom.
