A very small and minimalistic desktop temperature / humidity gauge. Ventilation holes on the sides and back help to get accurate readings.

Enclosure Dimensions: H 40mm X W 60mm X L 40mm

The LCD gauge was purchased at Amazon for around $3 USD and simply snaps into the enclosure after removing the supports. (see picture for gauge dimensions) They can be found but searching for: Mini Digital Humidity Thermometer. My version is from the company Veanic.

I assume this could also work in a refrigerator, cigar humidor and other similar applications where temperature and humidity need to be monitored.

Update 6/21/21: Version 2 has slightly larger side cutouts for better airflow. Both designs are functional

I set my supports to start at 70 degrees. This should help minimize post-printing tasks.

Do not forget to remove the inside support before installing the temp / humidity sensor.
