The prompt
Design a rectangular electronics enclosure box for PLA 3D printing. Internal dimensions: 250mm length, 95mm width, 45mm height. Main wall thickness: 3mm. Include a screw-on top lid with a 1.5mm recessed lip around the top perimeter of the box body. At the internal bottom corners, add four mounting screw bosses (7mm outer diameter, 3mm inner hole, elevated 5mm from the base) with small triangular gussets at their bases. On one short side (95mm), add a rectangular cutout of 20mm x 15mm. On the opposite short side, add ten 4mm ventilation slots. On the front panel (195mm side), from left to right, add: 1) a vertical stack of four rectangular cutouts for XT60 connectors (each 16mm wide x 8.5mm high, 2mm vertical gap, centered); 2) a rectangular cutout for a voltmeter (22.5mm wide x 10.5mm high); 3) a rectangular cutout for a power switch (19mm wide x 13mm high). Maintain 12mm horizontal spacing between these front panel sections.
