How it was made

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

Harp for the Elven Treetop 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. This is one part of the Elven Treetop City kit (Low-poly style, flat-lowpoly direction): Platforms and bridges high in giant trees. Use ONLY the kit palette, by name: leaf green #3a883a, silver #b9bfc6, bark brown #6b4a2e, soft gold #cfaf59, leaf green dark #235223, silver dark #8f99a3, leaf green light #5db15d, silver light #e4e6e7, 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 `season` (0–1, default 0.5) for the kit's "Season" setting wherever it makes sense on this part, and keep that id.

Note: About 0.66 m wide, 1.2 m tall (1.15 m frame plus crown), 0.32 m deep at default params; scales with the height param. Season changes leaf count, size and which kit green the leaves use (leaf green light below 0.34, leaf green to 0.67, leaf green dark above) and only affects the leaf ornament. Part ids use the root 'harp' because the plan checker rejects hyphens in ids. Static model, no animation.
