How do you remove this vent?

How do you remove this vent--I am tracking down a rattle.

 

I have the large dash trim piece off and can undo the snap at the top of the vent but then it just rotates down alitle and that is it. How do you finish it? I am trying not to break it.

I believe it pull straight out. If I'm not mistaken, they're mounted on the pivots and just snap into place.
