Turning wheels

A low-poly Bicycle City street sculpture: four bicycle wheels of three sizes hung in front of and behind a canal-green mast on a brick plinth. It comes with a seamless 8 s loop in which the wheels counter-turn on their own axles.

How it was made

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

Turning wheels for the Bicycle City 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. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Bicycle City kit (Low-poly style, flat-lowpoly direction): Streets made for bikes. Use ONLY the kit palette, by name: brick red lanes #c32222, canal green #3a883a, bright bike colours #b39d80, cream #f1e7d0, brick red lanes dark #821717, canal green dark #235223, brick red lanes light #db5757, canal green light #5db15d, 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 `bikeColours` (0–1, default 0.5) for the kit's "Bike colours" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 1.55 m wide, 0.88 m deep (the plinth) and 2.90 m tall. The plinth is 0.88 m square and 0.51 m high, and the wheels are real bicycle sizes: two 0.70 m (28 in), one 0.60 m (24 in) and one 0.50 m (20 in). The origin is at the bottom centre, the plinth rests on y = 0, and the front faces +Z. The exported model has 3,836 triangles in 28 meshes. Every material is named exactly after its kit palette colour. The exporter writes one material per mesh, so a colour name can appear on several materials: recolour by name. dark wood is not used. The baked clip scene-motion (8 s, seamless) only rotates the four wheel nodes about their own hub centres (local Z). The front wheels turn 1 whole turn and the back wheels 2 and 3 turns the other way. The plinth, mast and arms never move. The export snapshots a mid-loop frame, so the glTF's static node pose is a frame from the clip: play the clip, or seek it to 0, for the rest pose. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. bikeColours (the kit's 'Bike colours') sets how many of the four rims are painted, from round(value × 4): 0 leaves every rim mid grey, and the default 0.5 paints the top rim brick red and the right rim canal green. armReach moves the side wheels in or out. wheelSize scales all four wheels. Front and back wheels sit in separate planes, so they never touch across either range. glb-lint: 0 errors and 5 heuristic warnings. Two are about material count and duplicates, both caused by the per-mesh materials. One flags non-indexed geometry, which is deliberate flat shading. One flags overlaps where the bricks are deliberately nested round the mortar core. The last flags the 2.9 m height against the 1 m reference, which is the real size. The verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes on a copy with de-hyphenated ids; its part-id regex rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 8 survive the GLB reload.

About the Turning wheels 3D model

Turning wheels is a free animated low-poly 3D model from the Bicycle City set. It measures 1.6 m × 2.9 m × 88 cm (W × H × D) at real-world scale and is built from 3,836 triangles across 28 meshes, with 8 named parts and a baked animation (8.0 s). Download the 306 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.

Is the Turning wheels 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), 306 KB: 3,836 triangles, 7,488 vertices and 28 materials, modelled in metres at 1.6 m × 2.9 m × 88 cm.
Is Turning wheels animated?
Yes — the GLB carries a baked animation (8.0 s), ready to play with any glTF animation mixer.
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 Turning wheels 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.
