Small enclosure for projects powered using a CR123A 3v cell. The enclosure consists of a base and a lid. It is a snap fit. I've included vented and non-vented lid models.

I used mine to hold my ESP8266 powered temperature/humidity sensors, as per the pictures.

I love using CR123A with ESP8266 projects. I just power the ESP straight from the cell. Utilising deep sleep I get about a year our of a single cell, waking up, taking a reading, sending it to MQTT over ESP-Now, and then going back to sleep.

For indoor use only, I have not designed this to be waterproof.
