solar agarbatti dryer 3d model

Create an accurate 3D engineering model matching the reference image. Design a compact Smart Solar Agarbatti Dryer & Packaging System: tall rectangular metal cabinet, solar panel on top, transparent front door, four circular rotary drying trays stacked vertically, central vertical shaft, and radial agarbatti sticks on each tray. Each tray must have 3 equally spaced supports at 120° holding sticks at an inclined angle, with adjustable angle holders. Include one bottom blower with a four-way air distribution manifold for uniform upward airflow through all trays, top exhaust, temperature/humidity sensors and ESP32 control unit. Add tray tilt-and-slide release and a compact automatic bundling/sealing mechanism at the bottom. Keep proportions and component arrangement close to the reference. Clean realistic CAD geometry, modular and 3D-printable parts. No people, smoke, decorations or text.
