Gym floor
A low-poly 4 × 4 m gym floor tile: maple plank sports flooring with a blue rubber training mat framed by orange bevelled edge ramps, a white agility ladder painted across the front, and loose gym gear — flat bench, hex dumbbells, kettlebell and medicine ball. Its edges are flat and the planks and ladder run straight through, so copies tile seamlessly in every direction.
Left rail: colours and the 3 knobs the agent wrote into this model — they rebuild the geometry and go into your download. Right rail: looks for the viewer. Drag to orbit, scroll to zoom.

The brief given to 1DesignTool's “3D object” template:
Gym floor for the Sports Centre 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. Make it a ground piece on an exact 4 × 4 m footprint with flat edges at y = 0 that tile seamlessly with its neighbours in every direction; origin at the tile centre. This is one part of the Sports Centre kit (Low-poly style, flat-lowpoly direction): Courts, pool and gym. Use ONLY the kit palette, by name: court blue #2e67b8, wood #7d5736, white #f4f1ec, energy orange #ed7e1d, court blue dark #1f457a, wood dark #47321f, court blue light #6190d1, wood light #ac7d53, 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 `sportOnCourt` (0–1, default 0.5) for the kit's "Sport on court" setting wherever it makes sense on this part, and keep that id.

Note: Size: exactly 4.00 × 4.00 m. The origin is at the tile centre, the bottom rests on y = 0 and the front faces +Z. The dark-wood subfloor is 0.03 m thick and the plank walking surface is at 0.05 m. The rubber mat top is at 0.075 m. The tallest item at the default settings is the bench pad at 0.505 m. How it tiles: the slab edges are flat and full height. Plank seams sit half on each edge, so neighbours share one full seam. The planks run along X, and their rows divide 4 m evenly. The agility ladder rails cross the full width in X, and the rungs are every 0.5 m, so the ladder continues straight into the next tile along X. The mat and gear stay inside the tile. sportOnCourt (the kit's 'Sport on court') sets how much gym gear is on the mat, in this order: flat bench, dumbbell pair, kettlebell, medicine ball, plate stack, plyo box, blue kettlebell, second dumbbell pair. At the default 0.5 it shows the first four items. At 0 the mat is bare, and at 1 all eight items are out. The GLB is baked at the default params (1568 triangles, 16 meshes, static, no animation clip). matSize and plankRows rebuild only in the viewer. All gear was rendered and checked at sportOnCourt 1 with the smallest mat and stays on the mat. Every material is named after its kit palette colour, so you can recolour by name. The exporter writes one material per mesh, so some names repeat (16 material entries, 9 distinct colours in the default GLB). Warm white is not used. Court blue and wood dark appear only once the gear count reaches the plyo box and the blue kettlebell. The viewer uses exposure 0.72 instead of the direction's 1.05 so the palette does not wash out to pastel. This does not affect the GLB. glb-lint: 0 errors and 5 heuristic warnings, all expected: the material count and duplicate warnings come from the per-mesh export; geometry is non-indexed because it is flat-shaded; the overlap warnings are dumbbell grips inside their heads and the two plank tones sharing one footprint; the paint, mat, ramp and bench register as 'detached' because they sit on the slab rather than reaching y = 0. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen. The same plan passes with the slug de-hyphenated. three-check accepts the ids, and all 7 survive the GLB reload.
About the Gym floor 3D model
Gym floor is a free low-poly 3D model from the Sports Centre set. It measures 4.0 m × 51 cm × 4.0 m (W × H × D) at real-world scale and is built from 1,568 triangles across 16 meshes, with 7 named parts. Download the 150 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
- Is the Gym floor 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), 150 KB: 1,568 triangles, 4,193 vertices and 16 materials, modelled in metres at 4.0 m × 51 cm × 4.0 m.
- Can I animate Gym floor?
- It ships as a static mesh. Its 7 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 Gym floor 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.
