LEDs

A short indicator strip from the Circuit City kit: four 5 mm through-hole LEDs standing on their legs on a green circuit board, wired with gold traces to a small black driver chip. Flat low-poly, real component scale.

How it was made

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

LEDs for the Circuit 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 Circuit City kit (Low-poly style, flat-lowpoly direction): The inside of a computer as a city. Use ONLY the kit palette, by name: board green #3a883a, gold traces #d0a225, black chips #151619, led colours #988e81, board green dark #235223, gold traces dark #8f7019, board green light #5db15d, gold traces light #debd63, 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 `ledColours` (0–1, default 0.5) for the kit's "LED colours" setting wherever it makes sense on this part, and keep that id.

Note: Real component scale: the strip is 0.0317 m long × 0.015 m deep × 0.0136 m tall (5 mm LEDs on a 1.6 mm board), origin at bottom centre, resting on y = 0, front (power bus) facing +Z. 1920 triangles, 9 materials, each named exactly after its Circuit City palette colour, no textures, no animation. Normals are baked flat, so the facets survive in any engine. ledColours (default 0.5) rotates the four kit lamp colours (led colours, board green light, gold traces light, warm white) across the domes. At 0.5 they read gold-light, warm white, led colours, green-light from left to right. ledCount, pitch and standoff rebuild the board, traces and part list (LED ids run led-1 … led-N). The GLB reflects the default values only. glb-lint: 0 errors. Its overall verdict prints UNVERIFIED only because no requirements contract exists. Two heuristic warnings were reviewed and accepted: the pads, traces and silkscreen overlap the board on purpose, and the scale warning comes from the true 1.4 cm height. Assembly groups use plain ids (leds, leds.pcb, leds.driver, leds.ledN) because the kit plan grammar has no hyphens. Every mesh carries a circuit-city-leds.* id. The domes are opaque flat colour, not glowing; the GLB has no emissive or bloom.
