Open-Top Sensor Enclosure Base

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 length) by 69.0 mm (Y-axis width) by 45.0 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. The resulting interior hollow space must be exactly 90.0 mm by 65.0 mm. 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) to accommodate a lid weather-seal. 3. Full-Height Corner Bosses: In the four extreme interior corners of the box, model four solid cylindrical screw bosses. CRITICAL REQUIREMENT: These bosses (6.0 mm outer diameter, with a 2.5 mm inner pilot hole) must extrude vertically from the interior floor all the way up to sit completely flush with the top rim of the box (extruding exactly 43.0 mm from the inner floor). 4. Internal Partitioning (Two-Zone Layout): Extrude a 2.0 mm thick solid internal partition wall spanning the entire 90.0 mm X-axis. Position this wall to split the Y-axis into two distinct chambers: a larger bottom chamber (32.5 mm internal Y-width) and a smaller top chamber (30.0 mm internal Y-width). Cut a 5.0 mm circular pass-through hole completely through the center of this partition wall for wire routing. 5. Bottom Chamber (Electronics Core): Inside the larger bottom chamber, extrude four 5.0 mm tall cylindrical standoffs (3.5 mm OD, 1.5 mm ID) on the floor to mount a microcontroller. Cut a 10.0 mm wide by 5.0 mm tall rectangular USB port completely through the right exterior wall, aligned with this chamber. 6. Top Chamber (Sensor Zone): Left Side: Extrude four 5.0 mm tall cylindrical standoffs (3.5 mm OD) on the floor to mount a square sensor. Cut louvered ventilation slots through the left exterior wall aligned with this specific area. Right Side: Extrude two vertical U-channel guide rails extending from the floor to the top rim, spaced 15.5 mm apart to friction-fit a sliding PCB. Cut parallel vertical ventilation slots (1.5 mm wide) through the right exterior wall aligned with these rails. 7. Exterior Mounting: On the flat exterior bottom face of the main box, cut two horizontal grooves (3.75 mm wide, 1.25 mm deep) spanning the full X-axis to act as zip-tie strap channels.
