> when I hang it from the ceiling everything will line up with their actual azimuth to the horizon
I guess that makes sense at high latitudes. More generally, if you align the plane of rotation of the orrery with the ecliptic, and rotate it just right, then the positions of the sun and planets wrt the centre of the orrery should match their actual altitude and azimuth.
