Enclosure for the "Root" plant monitoring sensor

Summary

This is a 3D printed enclosure designed for my solar-powered smart plant monitor project.

It houses:
🌱 A single 18650 lithium-ion cell (with holder)
🔋 Integrated charger + BMS PCB
🌞 A 1W solar panel (mounted on the back)
📡 A Root plant monitoring sensor and Sprig-C3 ESP32 dev board

The enclosure keeps all components protected, while leaving room for airflow and easy access to the connectors. Its rectangular shape also makes it simple to mount near or inside a plant pot.
The case is printed in PLA with 3–4 perimeters for strength, but other materials (like PETG) may be used for better weather resistance.
Perfect for DIY smart gardening projects, especially if you’re experimenting with Home Assistant automations, Arduino, or custom ESP32 firmware.
