Louvered vent with screw on 12v fan mount

Threaded vent and a screw on mount for a 12v fan.  This is used as an exhaust fan for my DIY outdoor solar generator.  I needed a water to exhaust hot air from the solar charge controller and inverter contained in the box, but wanted a louvered vent design to help prevent water intrusion from rain.

Printed vent and fan mount in PETG to better withstand some outdoor conditions.  Gasket printed in TPU to help with water intrusion into the solar generator.

The 12v fan is controlled by a relay that is driven by an esp8266 running esphome, which is in turn powered by a 100AH 12v LIFEPo4 battery (part of the solar generator)
