The prompt
Create a single-piece, lightweight but strong eBAJA front steering knuckle. Use millimetres. Caster: 4°. Kingpin inclination: 6°. Upper-to-lower suspension joint centre distance: exactly 152.4 mm (6 inches). Hub mounting spacing: 111 mm. Brake rotor: 200 mm outer diameter. Caliper mounting-hole spacing: 55 mm centre-to-centre, with 8.5 mm holes for M8 bolts. Caliper mounting spacing: 95 mm. Caliper pad gap: 14.5 mm. Ear offset: 4.5 mm. Allow clearance for the KBX2 caliper. Include reinforced upper and lower suspension bosses, steering tie-rod arm, structural ribs, smooth fillets and CNC-friendly surfaces. CRITICAL: Keep the entire central bearing housing solid. Do not create any bearing bore, bearing seat, axle passage or central hole. I will machine this later. Build the entire knuckle as ONE continuous, fused solid. No separate or touching-only solids. Do not invent missing dimensions. Preserve all specified mounting positions and angles.
