Tinkercad Smart Park 3D Model

I need a complete Tinkercad model that showcases a forward-thinking public park. The core layout should feature solar-powered benches, Wi-Fi hotspots, smart lighting, and trash bins that automatically sort recyclables, all wired together in a way that would make sense for a real-world deployment.

For this iteration I want to place special emphasis on two points:

• Air-quality sensors must be integrated and clearly visible in the scene—they are the priority smart add-on.
• The solar benches should look sleek and contemporary; their aesthetics take precedence over raw charging capacity.

Beyond that, feel free to suggest extras such as rain-water harvesting or environmental dashboards if they complement the primary brief without cluttering the model.

Deliverables I expect:
1. A shareable Tinkercad link and the exported .STL/.OBJ files.
2. A short walkthrough (screenshots or 1-minute screen capture) highlighting where each smart feature sits and how it interacts.
3. A note on the components used so students can replicate the build in class.

Please attach examples of past work—especially any IoT or smart-city scenes you’ve built—so I can gauge style fit quickly.
