The prompt
Design a 3D-printable electronic enclosure box measuring 160mm length, 130mm width, and 110mm height. Wall thickness is 4mm. The top of the box is completely open for a lid. On the inside of the left and right walls, create vertical guide slots that are 10.6mm wide and cut 2mm deep into the plastic to slide in 10mm styrofoam sheets. On the right exterior wall, create a stepped cutout for a Peltier cooling kit: the inner pass-through hole must be 40mm x 40mm, and the outer recessed window must be 92mm x 92mm to cleanly seat a standard 92mm exhaust fan. Just below this exhaust window, add a small 5mm x 4mm U-shaped cable channel cutting through the wall. On the front exterior face of the box, add four M3 screw mounting holes arranged in a rectangle with center-to-center spacing of 40.5mm horizontally and 32.5mm vertically to mount a W1209 thermostat board. The entire model must be unified, watertight, and optimized for FDM 3D printing.
