The prompt
Generate a 3D CAD model for a functional RC car featuring a tubular space-frame chassis design, optimized for Additive Manufacturing (3D Printing). The structure must include a defined driver's cockpit (cabin) area for scale realism. A primary engineering constraint is that the chassis must feature a secure, integrated internal mounting bay to house an Arduino Uno microcontroller board, ideally integrated seamlessly within the tubular structure or cockpit floor. The overall footprint of the vehicle must not exceed a maximum length of 30 cm (300 mm). Please include generic mounting points for a standard RC steering servo and motor mount, ensuring the tubular sections are thick enough for FDM printing stability without requiring excessive supports. Furthermore, recommend a specific durable 3D printing filament material (e.g., PETG, ABS, or Nylon) suitable for this type of structural RC application
