SBC-Q Charger Housing

--- 🧱 SBC‑Q — Full CAD Modeling Workflow (Export‑Ready) 1️⃣ Base Body Create the main housing block. Dimensions: • 160 mm width • 105 mm depth • 60 mm height Shaping: • Corner fillets: R4–5 mm • Front‑top chamfer: 2–3 mm • Optional top surface radius: R1 mm This forms the correct Shure charger silhouette. --- 2️⃣ Dual Battery Bays Cut two recessed cavities for SB900A batteries. Each bay: • 52 mm wide • 72 mm deep • 22 mm recess depth • 2° draft angle inward • R3 mm corner radius Placement: • 10–12 mm gap between bays • 8–10 mm margin from outer edges Extrude‑cut both bays. --- 3️⃣ Internal Bay Features Add the functional geometry inside each bay. Rear contact block: • 12 × 8 × 6 mm • Slight fillet • Flush against rear wall Alignment rails: • 1.5–2 mm thick • 10–12 mm tall • Run along left/right bay walls Top bevel: • 1 mm chamfer around bay opening --- 4️⃣ LED Indicators Add the status LEDs. LED geometry: • 4 mm diameter • 0.5 mm recess • Positioned front‑right of each bay Model as a small circular cut + lens extrusion. --- 5️⃣ Rear Panel Features Add the functional rear components. IEC inlet: • 14 × 10 mm rectangular cut • Slight fillet • Centered horizontally Vent slots: • 6–8 horizontal vents • 4 mm tall × 20–25 mm wide • 4–6 mm spacing • Positioned upper‑rear Label inset: • 40 × 20 mm rectangle • 1 mm recess --- 6️⃣ Bottom Plate Flip the model and add the underside details. Feet: • 10 mm diameter • 2 mm height • Rubber pads Perimeter inset: • 1 mm inward offset • 1 mm recess depth Internal screw posts: • 4 posts • 6–8 mm diameter • Positioned near corners --- 7️⃣ Materials & Finish Apply realistic materials. Body: • Matte black ABS • Roughness: 0.2–0.3 mm bump • Slight specular reflection LEDs: • Green • Amber • Red Contact block: • Metallic silver
