This replaces the original VTX cover. My cat chewed mine up, and also I needed something to vent air backwards after moving my camera to the nose & creating an intake there.

I printed this vertically (standing up), with supports. Block supports on the hole at the top. If you print it flat, the layer lines won't look very good. It's hollow and rounded, so you'll need supports no matter what, and vertically will get you the best results.
