UAE Barjeel Hydroponic Tower Wind-Catcher (Modular 3-Part)

Prompt: 3D-Printable UAE Barjeel for an Adaptive Hydroponic Tower Design a practical, modular, 3D-printable wind-catcher head inspired by the traditional Emirati Barjeel (wind tower), intended to be mounted on top of a vertical hydroponic growing tower. Main design requirements: 1. Traditional Barjeel appearance: A square wind-catching head with four directional openings, inspired by traditional UAE architecture, with a clean modern engineering aesthetic. 2. Airflow channels: Include internal vertical air passages that guide incoming outdoor air downward alongside the plants. Add separate outlet openings near the lower section to allow air to escape and encourage natural ventilation. 3. Modular construction: Separate the design into a removable wind-catcher head, an adapter connector, and an optional internal air-guiding duct. 4. 3D-printable geometry: Use solid walls, practical wall thickness, rounded edges where appropriate, no unnecessarily complex overhangs, and minimal support requirements. 5. Assembly: Use simple snap-fit or screw connections where practical. Make the bottom connector customizable to fit different hydroponic tower diameters. 6. Water and electronics protection: Keep the air channels separate from the nutrient-water pipe and all electrical components. Avoid designs that direct rainwater into the reservoir. 7. Prototype dimensions: Start with an approximately 120 mm × 120 mm square head and an overall head height of approximately 100–120 mm. Treat these as adjustable starting dimensions, not final validated dimensions. 8. Material: Design for PETG or PLA 3D printing. PETG is preferred for outdoor heat and moisture exposure, but the finished part must still be tested in the intended environment. 9. CAD deliverables: Generate a fully editable parametric CAD model, an exploded assembly view, dimensioned orthographic drawings, and separate STL files for each printable component. If supported, also provide STEP files. 10. Engineering validation: Do not claim that the design guarantees water cooling or a continuous natural draft. Make airflow passages inspectable and easy to clean. Clearly identify any dimensions that must be measured before final printing. Prioritize a functional, lightweight prototype that can be printed and tested before designing the full hydroponic tower. Do not add fans, motors, or electronic components.
