The prompt
Design a parametric 3D printable chassis box with a removable top lid. Outer dimensions: 12.0 cm width, 12.0 cm depth, 15.0 cm height. Wall thickness: 0.3 cm uniformly. Features: 1. Top Lid: Recessed top frame measuring 12.0 cm x 12.0 cm x 0.8 cm with a flush center cutout measuring 11.0 cm x 11.0 cm x 0.4 cm deep for an integrated solar panel. 2. Side Vents: Two opposite side walls feature angled louvers pitched at 45 degrees over an 8.0 cm width by 9.0 cm height area for passive airflow. 3. Front/Side Port: One precise rectangular cutout measuring 1.6 cm width by 0.9 cm height on the lower right outer panel for a USB-C port interface. 4. Internal Standoffs: Four internal vertical mounting pillars with M2.5 screw holes spaced at 9.2 cm x 7.2 cm grid pattern on the interior floor for board mounting. 5. Base: Bottom plate 12.0 cm x 12.0 cm x 1.2 cm with 4 corner recessed sockets (1.5 cm diameter, 0.6 cm depth) for rubber feet.
