SONOFF SNZB-02WD Thermometer Outdoor Enclosure

This 3D model is a two-part protective enclosure designed specifically for the Sonoff SNZB-02WD thermometer/hygrometer. 

It allows you to mount the sensor outside a window while keeping it protected from environmental factors that can distort readings.

The enclosure acts as a passive radiation shield, helping to ensure more accurate temperature measurements by reducing exposure to direct sunlight and allowing proper airflow.
