The prompt
Generate a 3D printable, two-part electronics enclosure consisting of a main chassis (base) and a flush-fitting lid. The overall assembled dimensions are 104mm length, 84mm width, and 49mm height with 4mm rounded exterior corners. The walls must be exactly 2mm thick. Base Chassis details: Hollow interior cavity (100mm x 80mm x 43mm deep). Four cylindrical screw bosses in the interior corners for M3 screws. Four internal 5mm tall cylindrical standoffs (spaced for an 80x60mm PCB) in the bottom. Left wall: A 12mm x 7.5mm rectangular cutout for a USB cable. Right wall: A 27mm circular exhaust cutout with a built-in cross-shaped finger guard, surrounded by four 3.2mm screw holes spaced exactly 24mm apart for mounting a 30x30mm fan. Bottom wall: A row of nine vertical intake ventilation slits (2.5mm wide, 26mm tall) for passive airflow. Top wall: A row of five vertical ventilation slits (2.2mm wide, 18mm tall). Two external mounting ears (flanges) with keyhole slots on the back for wall mounting. Lid details: Flat 2mm thick rectangular plate measuring 104mm x 84mm with 4mm rounded corners. A 2mm deep recessed inner alignment lip that fits precisely inside the base chassis. Four 3.4mm countersunk holes in the corners aligning with the base bosses. A 24.5mm x 14.5mm rectangular cutout window for an OLED screen. A circular sound grille consisting of one central 3mm hole surrounded by six 2.5mm holes spaced radially for a buzzer. Ensure the geometry is fully manifold, hollowed correctly, and optimized for FDM 3D printing without requiring internal support structures.
