The prompt
Design a two-part 3D printable enclosure for a custom PCB. Part 1: Main Bottom Case - Create a hollow rectangular box. The INTERNAL dimensions must be 41.6 mm width, 33.3 mm length, and 7.0 mm depth. - The wall thickness for the bottom and all side walls should be exactly 2.0 mm. - Add four cylindrical screw bosses (standoffs) inside the four inner corners. Each boss should have an outer diameter of 6.0 mm and an inner hole diameter of 2.5 mm (for M3 screws), extending from the bottom to the top edge of the walls. - On the front long wall, cut a rectangular hole for a USB-C port. The cutout must be 9.5 mm wide and 3.0 mm high. Position it at the bottom edge, starting exactly 6.2 mm from the right inner corner. - On the right short wall, cut a through-hole for an SMA connector. The hole diameter is 5.8 mm, placed in the center of the wall. On the outside face of this wall, add an 8.0 mm hexagonal recess centered over the 5.8 mm hole to lock the SMA nut. Part 2: The Lid - Create a flat rectangular plate for the lid. Its outer dimensions must match the outer dimensions of the bottom case (45.6 mm width x 37.3 mm length), with a thickness of 2.0 mm. - Add four 3.2 mm through-holes in the corners. These holes must perfectly align with the screw bosses in the bottom case.
