Antenna pins

A pin-header tile from the Circuit City kit: two rows of tall gold square pins in a notched black plastic carrier, standing on a green circuit board with copper traces, vias and a small status LED. They read like a cluster of radio masts on a city block. Flat low-poly, real component scale.

How it was made

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

Antenna pins 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 tile is 0.0167 m wide × 0.0129 m deep × 0.0101 m tall. That is a 1.6 mm board, 2.54 mm-pitch 0.64 mm square pins, a 2.5 mm carrier and a 1206 LED. Origin is at bottom centre, resting on y = 0, and the front (status LED) faces +Z. The model is 1000 triangles with 10 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) picks the status LED's lens: below 1/3 board green light, from 1/3 to 2/3 led colours, above that warm white. At warm white the lens shares that colour name with the silkscreen, so the GLB then lists warm white twice. pinColumns, pinRows and pinHeight rebuild the board, traces and carrier. 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: via holes, silkscreen and the LED lens nest into their neighbours on purpose, and the scale warning comes from the true 1 cm height. Pins pass through the carrier and sit 0.3 mm into the board, like through-hole parts. Assembly groups use plain ids (antenna, antenna.board, antenna.header, antenna.led) because the kit plan grammar has no hyphens. Every mesh carries a circuit-city-antenna-pins.* id.
