Core Objective: Generate a high-resolution, manufacturing-grade 3D model (STL/OBJ/STEP) of the current generation BMW 740Li (G70). The model must be a 1:1 scale digital twin, capturing every aerodynamic contour and luxury detail with absolute precision for high-end 3D printing on a Bambulab X1C. Exterior Architecture & Bodywork: The body must exhibit the long-wheelbase silhouette of the 'Li' variant. Focus on the massive, illuminated Iconic Glow kidney grille with vertical slats. The split-headlight design is critical: the upper crystal-effect LED strips must be distinct from the lower main matrix beams. Every panel gap and shut line—around the doors, the long hood, and the trunk—must be modeled with a depth of 0.5mm for realistic shadow casting. Include the flush-integrated door handles and the distinctive 'Hofmeister kink' on the C-pillar with its textured triangular pattern. Rear & Underside Detail: The rear must feature the slim, horizontal L-shaped LED taillights with internal 3D structures. Incorporate the integrated exhaust outlets within the rear apron and the subtle rear diffuser. The underside should not be a flat plane; it must include the basic suspension geometry, the exhaust routing, and the protective aerodynamic underbody shielding to ensure structural rigidity when printed. Wheels & Technical Elements: Model the 21-inch M-Aerodynamic wheels (Style 909M) with multi-spoke complexity. The brake calipers must be visible behind the spokes, featuring the 'M' logo engraving. Tires should have realistic sidewall markings and a detailed tread pattern suitable for high-resolution nozzle extrusion. Interior & Glass: The model should be 'manifold-solid' for printing. If an interior is included, prioritize the BMW Interaction Bar—the crystalline faceted structure running across the dashboard. Model the curved display housing and the intricate 'diamond' stitching on the Merino leather seats. Ensure the panoramic Sky Lounge glass roof frame is perfectly aligned with the roofline. Technical Specifications for AI Generator: Geometry: High-poly count (minimum 5 million polygons) to avoid faceting on curved surfaces. Surface Finish: Class-A surfacing with G2 continuity to ensure a mirror-like finish after post-processing. Optimization: Ensure the mesh is "watertight" with zero non-manifold edges, optimized for slicing in Bambu Studio. Scale: Default 1:1 real-world dimensions, allowing for perfect downscaling to 1:18 or 1:24.
