Is the Conveyor lines 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), 215 KB: 1,916 triangles, 5,748 vertices and 34 materials, modelled in metres at 4.3 m × 1.7 m × 1.4 m.

Can I animate Conveyor lines?

It ships as a static mesh. Its 9 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 Conveyor lines 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.

Conveyor lines

A low-poly 4 m belt-conveyor section for a robot factory: a black cleated belt between electric-blue side frames on light-grey legs, with an orange-geared drive motor, a stack light and a control pedestal, carrying half-built white robot torsos and heads on trays.

How it was made

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

Conveyor lines for the Robot Factory 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 Robot Factory kit (Low-poly style, flat-lowpoly direction): A clean line that builds robots. Use ONLY the kit palette, by name: white #f4f1ec, light grey #a3a5a8, electric blue #136dec, orange #ed7e1d, white dark #d7cebc, light grey dark #7c7f83, white light #f9f8f6, light grey light #cccccc, 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 `lineSpeed` (0–1, default 0.5) for the kit's "Line speed" setting wherever it makes sense on this part, and keep that id.

Note: Size: 4.3 m long × 1.42 m deep × 1.70 m tall to the stack-light cap; the belt is 0.7 m wide and its surface sits at 0.9 m working height. Origin is at the bottom centre of the bounds on y = 0; the control pedestal and drive motor face the front (+Z). 1,916 triangles, static, no animation clip. Normals are baked flat (non-indexed geometry) so the facets survive in engines that ignore flat-shading flags. Each part is merged to one mesh per colour; the exporter still writes one material per mesh, so the same colour name appears on several materials: recolour by name. 9 of the 12 kit colours are used; white dark, warm white and dark wood are not. The GLB is baked at default params. lineSpeed (kit 'Line speed') swings the speed lever on the control panel from far left (stopped) to far right (full) and widens the spacing of the robot parts on the belt from 0.85 m to 1.5 m. The belt does not move. length, beltWidth and itemCount change the geometry only when the scene is rebuilt in the viewer. glb-lint: 0 errors and 5 heuristic warnings: material count above the direction default (one per mesh), duplicate-named materials, non-indexed primitives (intended flat normals), overlapping merged-part bounds, and parts that rest on another part's group (trays on the belt, frames on the legs, the gearbox on the frame) flagged as detached. plan-check fails only on its part-id regex, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 9 survive the GLB reload.
