ESP32-C6 + SCD-41 Sensor Enclosure

ESP32-C6 + SCD-41 Sensor Enclosure

This is a simple enclosure designed for an ESP32-C6 paired with an Adafruit SCD-41 CO₂ sensor.

This is my first 3D model, so there may be imperfections or things that could be improved. That said, it prints well and works reliably for my setup. If you notice issues or have suggestions, feel free to modify or adapt the design.

The case is intended for basic air quality monitoring (CO₂) using ESPHome.

Features:

* Compact enclosure for ESP32-C6 + SCD-41

* Ventilation for accurate sensor readings

* Simple, functional design

* Depending on your printer and tolerances, you may need minor adjustments.
