Thank you for the help, everyone! I was thinking of a gimbal. I have seen vanes, but I think there is an inherent drawback to those. If you utilize a single vane, you are only deflecting half of the airflow. If you increase the number of vanes, you could be seriously restricting the airflow.
I have an idea in my rock-filled head for an easy gimbal joint based on the info share here. I'll see how it goes when I get around to it!
