We chose to 3D print our enclosures because it gives us complete control over the design while keeping costs practical for a prototype system. PETG filament offers weather resistance and durability for outdoor use, and 3D printing lets us create custom shapes that fit our components without wasting space or material. More importantly, it allows us to iterate quickly: if we need to adjust a mounting point or change the sensor positioning, we can redesign and print a new version in hours rather than waiting for manufactured parts. For a capstone project where we're learning and refining as we go, that flexibility is invaluable.
