Is the Window Cleaner 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), 460 KB: 4,026 triangles, 15,552 vertices and 19 materials, modelled in metres at 1.7 m × 1.8 m × 47 cm.

Is Window Cleaner animated?

It ships without a baked clip, in its bind pose. It is rigged with a 25-bone Mixamo-compatible skeleton, so it takes retargeted animation.

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 Window Cleaner 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.

Window Cleaner

A calm, athletic window cleaner in his 40s built from voxel cubes: sky-blue overalls, orange safety harness, cap and rubber boots, with a squeegee in his right hand and a bucket hooked to his belt. Rigged on the library's shared Mixamo skeleton in T-pose.

How it was made

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

A man, 40s, athletic, about 1.78 m tall. Calm, concentrating expression. Wearing: blue overalls, safety harness, cap, rubber boots (plain fabrics, no logos, brand names or readable text). Palette: Sky blue, orange harness. Prop: squeegee and bucket, carried naturally and bound to the hand or arm bone that holds it. Voxel style. The rig test is judged by eye from dist/rig-test.png: in the bent pose every limb, sleeve and the prop must stay attached and deform with the body — verify the capture visually before reporting PASS.

Note: Static T-pose bind with no animation clips. 25 mixamorig bones (Hips, Spine, Spine1, Spine2, Neck, Head, HeadTop_End, Shoulder/Arm/ForeArm/Hand and UpLeg/Leg/Foot/ToeBase/Toe_End on each side). No finger bones: the hands are voxel blocks driven by mixamorig:LeftHand/RightHand only. Each bone's local +Y points along the bone toward its child. Eight skinned meshes share one skeleton; the measured maximum is 3 influences per vertex. The squeegee is weighted 100% to mixamorig:RightHand. The bucket hangs from the belt on the left hip and is weighted 100% to mixamorig:Hips, so it follows the pelvis, not a hand. The GLB has 19 material slots: the exporter writes a separate copy of each shared material per mesh, but there are only 12 colour roles. 4,026 triangles. glb-lint reports 0 errors with the quality-requirements.json contract (verdict PASS); without a contract it reports 0 errors and an UNVERIFIED verdict. The remaining warnings are heuristics: duplicate material copies, the harness overlapping the overalls (it is worn over them), and the cap and bucket flagged as detached.

About the Window Cleaner 3D model

Window Cleaner is a free voxel 3D model from the City and office characters set, rigged with a 25-bone Mixamo-compatible skeleton. It measures 1.7 m × 1.8 m × 47 cm (W × H × D) at real-world scale and is built from 4,026 triangles across 19 meshes, with 8 named parts.
