bmw sedan 3d model

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. Incorporat
