Spray proof vent test piece meant for electronic housing for another project but works so well I'm uploading it by itself. Hopeful helpful for someone else.

Inspired by Slant3D's youtube video with some improvements. But I don't really like with how he sells these as “waterproof” so I want to set the expectation: Water does seep though it slowly, and whatever the vent's attached to need to have a way to drain out the seeping water. It stops water from spraying on to what's behind it. Water seeping in will flow along the vent. Even when the vent was facing up water didn't drip down. Should be useful on RC boats or whatever electronic that need to resist rain.

It's not ready to be mounted like a vent. It was a cut-off of an electronic housing. So I included step file to make it easier to be integrated in other designs. Please post a make if you do that! Thx.
