The prompt
Generate a 3D CAD model for a functional RC car chassis designed for Additive Manufacturing (3D Printing). The primary engineering constraint is that the chassis must feature a secure, integrated internal mounting bay or compartment to house an Arduino Uno microcontroller board. The overall footprint of the chassis 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, optimized for FDM printing stability. Furthermore, based on the structural requirements, recommend a specific durable 3D printing filament material (e.g., PETG, ABS, or Nylon) suitable for RC hobbyist applications.
