Shipping Container Extra Vents

I made this part a few months ago for my shipping container to help dissipate the heat from the blaring sun. it turned out working out really good. They don't take long to print.

I cut a hole with a 1 inch pipe conduit connector size (electrical one inch size connector)
Put silicone on the base
pushed it in
cut a screen to cover the back to prevent skeeters and black flies from entering
and it worked out perfect, air flows nicely and water stays out.

With the rains we've been getting lately, I haven't seen any traces of water.
