Create a comprehensive prompt for generating an image of a modular container system optimized for 3D model generation and printing. The design should include the following features:
A robust, tough exterior that can withstand outdoor conditions while being lightweight.
A screw-on lid with secure threading to ensure airtightness and prevent leaks during transport.
Multiple size options available through extendable sections; users should be able to add different lengths or extensions as needed, allowing customization based on storage requirements.
An integrated hole designed specifically for attaching key rings or similar accessories without compromising structural integrity.
Various mount options engineered to securely attach the container atop vehicle racks; these mounts must feature quick-release mechanisms yet remain lockable using standard padlocks for added security against theft.
Additionally, consider incorporating:
Reinforced corners and edges in the design to enhance durability during rugged use,
Internal compartments within each section of the container that allow organization of smaller items,
Textured surfaces on grips or handles ensuring ease-of-use even when wet,
Design elements minimizing overhangs where possible—such as sloped lids—to facilitate smoother 3D printing processes.
The final visual representation should reflect all functional aspects while maintaining aesthetic appeal suitable for both casual consumers and serious adventurers alike."
