The prompt
Two-part rugged smartwatch enclosure for a regular ESP32 DevKit board (approx 51x28mm PCB, plus headers/USB). Printed as separate named parts: "body" and "lid". BODY: rounded hollow rectangular block, approx 62 x 40 x 22 mm outer, corner radius 6mm, wall thickness 2mm, open at the top. An internal dividing shelf (2mm thick horizontal ledge/plate with a cutout for wiring) at mid-height to separate the ESP32 board area from the battery/sensor area below. A 15x15mm square sensor window cutout through the bottom wall, centered. A 20mm wide strap slot (with bar space, ~4mm tall) through each short end of the body for a 20mm watch strap. LID: matching rounded-rectangle top cover, 2mm thick, with a lip that fits inside the body opening (0.3mm clearance), and a rectangular cutout for a small screen (approx 27 x 15mm viewing window, e.g. 0.96in OLED) centered. Rugged look: slightly raised bezel rim on lid. Export STL, lid shown separately beside the body.
