The prompt
Generate a 3D printable two-part electronic enclosure for a compact MP3 player. External dimensions: 70mm length, 45mm width, 20mm height. Wall thickness: 2mm, optimized for FDM printing. The enclosure consists of a bottom shell and a top lid. The lid must attach to the bottom shell using internal snap-fit joints. On the top lid face, create a precise rectangular window only for a screen. The rest of the lid face must be solid. Integrate exactly six circular 6mm diameter button holes into the enclosure walls as follows: On the top 45mm edge (near the screen), place one circular 6mm cutout, positioned away from the 3.5mm jack. On the right 70mm side face, add three evenly spaced circular cutouts, each 6mm in diameter, centered vertically along the side. On the opposite left 70mm side face, add two evenly spaced circular cutouts, each 6mm in diameter, centered vertically. Inside the bottom shell, add internal mounting standoffs to support an ESP32-S3-Zero board and a PCM5102 DAC module. Maintain the necessary cutouts: a USB-C port on the bottom edge, and a circular 6mm cutout for a 3.5mm audio jack on the top edge. Add small ventilation slots on the back face.
