The prompt
Design a modular, fabrication-oriented 3D CAD prototype of **SmartDrain: AI-Based Smart Drainage Detection and Automatic Safety System for Urban Flooding**. Create a physically plausible, small-scale hydraulic test rig using PVC/uPVC pipes, transparent acrylic sections, standard fittings, and 3D-printed brackets. Use millimetres (mm) and editable preliminary dimensions where specifications are unknown. **1. Drainage Network:** One main horizontal pipe connected to six smaller sub-pipes using realistic T-junctions, elbows, and removable inspection joints. Include transparent sections for observing water flow and simulating normal, partial, and critical blockages. Provide four sensor stations and accessible maintenance points. **2. Water Circulation:** Include a reservoir, DC water pump, inlet, outlet, secure hose connections, and a recirculating return loop. Provide removable joints for cleaning. **3. Sensors:** Add removable mounting brackets and protected ports for a water-level sensor, YF-S201 flow sensor, BMP280 pressure sensor (only with a compatible, range-appropriate pressure interface), and INMP441 acoustic sensor. Include an optional FSR contact point, cable channels, and labelled mounting positions. Keep electronics isolated from water. **4. Automatic Vent:** Add a high-point vent chamber with a servo bracket, mechanically linked flap, adjustable mounting slots, and travel stops. Prevent unsafe pressure buildup and uncontrolled water discharge. **5. Bio-Filter:** Include a removable filter chamber with inlet, outlet, lid, and replaceable media basket for demonstration filtration materials. Do not claim wastewater-treatment capability without testing. **6. Electronics:** Add an elevated, protected enclosure for the ESP32 DevKit V1, LM2596 buck converter, terminals, wiring, and pump/servo power connections. Include cable glands, mounting standoffs, USB access, and safe cable routing away from water and moving parts. **7. CAD Deliverables:** Generate the complete 3D assembly, exploded view, individual components, dimensioned front/top/side drawings, isometric rendering, component labels, mounting details, assembly sequence, and a bill of materials linked to the design. Export STEP files and STL files where supported. Prioritize realistic pipe geometry, fitting clearances, modular construction, replaceable sensor mounts, safe water/electrical separation, and ease of assembly. Clearly distinguish proposed design components from hardware already built and tested. Use editable parameters instead of inventing unverified fabrication dimensions.
