The prompt
Design a parametric two-piece clamshell enclosure for a Raspberry Pi 4B with a Waveshare RS485 CAN HAT. Reference geometry: use the official Raspberry Pi 4B mechanical drawing (pip.raspberrypi.com, part RP-008343). Case: 0.5mm clearance around the PCB, 2.5mm walls/floor/roof, split into upper/lower halves along a stepped parting line that passes through the vertical middle of each connector except the microSD. Press-fit joint on the parting line, sized with ~0.2mm clearance, automatically excluded wherever it would cross a port opening. Four U-shaped ears, 2 on each long side, with 5mm holes. Filleted corners/top edge. A roof vent (your choice of pattern) and a GPIO pins-1-6 access window.
