Free 3D library · 38 models

Free 3D models, built by an agent.

Game-ready GLB props, toys, vehicles and scenes. Every one was generated by 1DesignTool's 3D template — a coding agent following the design kit — so each model has named parts, real knobs you can remix, and a clean export. Free for commercial use. No sign-up.

How a model gets here

A paragraph in, a checked GLB out.

  1. 1 · The brief

    One paragraph per model, given to 1DesignTool's "3D object" template — the subject, its signature details and a triangle budget.

  2. 2 · The agent builds it

    Codex (GPT-6.1-Sol) follows the design kit's 3D route: picks a direction, builds from reviewed recipes, names every part and exposes real parameters.

  3. 3 · The kit checks it

    Deterministic captures, a GLB export, a lint of that GLB and a reload proof. Only models that pass are published.

The real brief for the windmill
“A tower windmill (~8 m): tapered stone tower, a conical thatched cap, four lattice sails with cloth that rotate in a baked seamless loop around a correct hub pivot, a wooden door and a small balcony.”
Drop it in

One URL. Any engine.

Every model is a single GLB on a CDN, in metres, +Y up, front facing +Z, sitting on the origin. Load it straight from the URL or download it into your project.

  • · Named parts — hide, swap or animate any piece by name
  • · Materials named by role — recolour the body in one line
  • · Baked clips on animated models — play them with a mixer
import { GLTFLoader } from "three/addons/loaders/GLTFLoader.js";

const gltf = await new GLTFLoader().loadAsync(
  "https://assets.stoicsoft.com/1designtool/3d/models/windmill/6e5fef551b/model.glb"
);
scene.add(gltf.scene); // metres, +Y up, front faces +Z

const mixer = new THREE.AnimationMixer(gltf.scene);
gltf.animations.forEach((clip) => mixer.clipAction(clip).play());
// in your loop: mixer.update(delta)

Questions

About the library

Are these really free?+

Yes. Every model is free to download and use in personal and commercial projects — games, apps, sites, renders, client work. No account, no attribution required. The one thing you can't do is re-sell or re-publish the files as a model pack of your own. The license page has the plain-language version.

How were they made?+

Each model started as a one-paragraph brief given to 1DesignTool's "3D object" template. Codex (GPT-6.1-Sol) then followed the design kit's 3D route: a short plan, a chosen direction (low-poly, lacquer toy, product, voxel…), construction from the kit's recipes with named parts, and a scene module with real parameters. The kit's checks verified each one — deterministic capture, a clean GLB export and a reload of that GLB — before it was published here.

What format are they in?+

GLB (binary glTF 2.0), in metres with +Y up and the front facing +Z, resting on the ground at the origin. three.js, Babylon.js, Blender and Godot open it directly; Unity and Unreal import it with their glTF importers. Materials are named by role (body, trim, glass…), so recolouring is one material away.

What does "remix" mean here?+

Each model is a small program, not a frozen mesh. Its scene declares parameters — tower height, sail length, drawer count — and the detail page runs that exact scene so you can move the knobs and download the result as a new GLB.

Can I get a model that isn't in the library?+

Make it. The same template that made these runs on your own machine in 1DesignTool with the coding agent you already use — describe the object and you get the scene, the GLB, PNG and OBJ exports.

Are more models coming?+

Yes. The library reads its catalog live, so new batches appear here without a site release.

Need one that isn't here?

Describe it to 1DesignTool. The same 3D template runs on your machine with the coding agent you already pay for — scene, GLB, PNG and OBJ included.
