The prompt
"Generate a 3D-printable modular assembly for a scale autonomous robot car, overall dimensions: 60cm length, 32cm width. The model must consist of TWO SEPARATE detachable components designed for M3 assembly screws (3mm diameter holes): PART 1: Lower Mechanical Chassis Frame (Length: 60cm, Width: 32cm, Thickness: 5mm) Heavy-duty structural base plate with reinforced mounting grids and wire routing slots. Four corner wheel-well cutouts with pre-drilled M3 screw hole patterns for mounting motor brackets and suspension arms. Dedicated mounting hole array (M3 size) arranged for an ESP32 microcontroller board, motor drivers, NRF24L01 module, NEO-6M GPS, and a central battery compartment. Four vertical corner mounting posts with M3 threaded holes on the outer edge to securely attach the outer car body shell. PART 2: Realistic Upper Automotive Body Shell (Length: 62cm, Width: 33cm, Height: 18cm) Aerodynamic outer body inspired by modern real-world sedan/coupe sports cars, featuring defined front grille, stylized headlights/taillight recesses, side door panels, roof, and realistic vehicle contours. Hollow interior design (3mm wall thickness) to comfortably cover and protect all internal electronics and sensors on the chassis. Cutouts for a front windshield/grille area suitable for mounting an ultrasonic sensor or TFT display screen. Four matching inner mounting tabs with M3 pass-through screw holes located precisely to align with the lower chassis posts for easy screw assembly."
