The prompt
Text-to-CAD Prompt: PyroWatch Main Enclosure Base (DHT11 & Boss Fix) Generate a 3D CAD model of an open-top rectangular electronic enclosure base. 1. Outer Body & Shell: Create a solid rectangular block with outer dimensions of 94.0 mm (X-axis) by 69.0 mm (Y-axis) by 40.0 mm (Z-axis height). Shell this block open from the top face down with a uniform 2.0 mm wall thickness on the floor and all four side walls. 2. Top Rim Seal: Along the entire top perimeter edge of the four walls, cut a continuous 1.5 mm deep by 1.5 mm wide recessed step (drip lip). 3. Full-Height Corner Bosses: In ALL FOUR extreme interior corners, model identical solid cylindrical screw bosses (6.0 mm OD, 2.5 mm ID pilot hole). ALL FOUR bosses MUST extrude from the interior floor all the way up to sit completely flush with the top rim of the box. Do not make them short. 4. Internal Partitioning: Extrude a 2.0 mm thick solid internal partition wall spanning the 90.0 mm X-axis, dividing the Y-axis into a 32.5 mm bottom chamber and a 30.0 mm top chamber. This partition wall must only be 18.0 mm tall from the floor. Cut a 5.0 mm circular pass-through hole through the center of this short wall. 5. Bottom Chamber: Extrude four 5.0 mm tall cylindrical standoffs (3.5 mm OD, 1.5 mm ID) on the floor. Cut a 10.0 mm wide by 5.0 mm tall rectangular USB port completely through the right exterior wall. 6. Top Chamber (Sensor Zone): Left Side: Extrude four 5.0 mm tall cylindrical standoffs (3.5 mm OD). Cut louvered ventilation slots through the adjacent left exterior wall. Right Side (DHT11 Mount): DO NOT make large blocks. Extrude two thin, discrete vertical guide rails protruding ONLY 3.0 mm inward from the right interior wall. These rails should be 2.0 mm thick and spaced exactly 15.5 mm apart to grip the extreme edges of a small PCB. Cut parallel vertical ventilation slots (1.5 mm wide) through the right wall between these rails. 7. Exterior Mounting: On the flat exterior bottom face, cut two horizontal grooves (3.75 mm wide, 1.25 mm deep) spanning the X-axis.
