Summary

I mounted my VTX in the nose cone right behind the camera, so I designed an air vent that can be cut into the cone that will flow over the VTX. But because I added a vent, I created a block for the existing canopy vent that fits rather perfectly. :)

Print both on their side so that you get a smoother surface. If you print flat you get those ugly layer lines, but if you print on the side they are nice and smooth on the exposed surface.

Tree type supports are needed for the air vent on its side. It will print without supports upright, just won't turn out as well.
