Small power box vent

Description

This is yet another small vent to be used to allow power supply boxes to breathe. My particular use is to install it in a Harbor Freight ammo box to cool the 12v power supply for pixel Christmas lights. The diameter of the threads is just under 1" so a 1" hole should work well. I printed the washer in TPU which will compress and seal the opening. The top of the vent is tilted away from the box to aid in rain runoff. There are no supports needed and printing of all of the parts should take about 2 hours.
