Photoshop :: 3D Object Rotation In CS5.5

I created a simple shape in Photoshop I then edited the shape using the Repoussé dialog. I simply extruded the object. The default extrusion depth setting of 1.0 was far too deep for my needs so I changed the depth to 0.07. It looked good. Next I wanted to animate my simple hexagon shape rotating about it's z axis.

So using the animation pallet, I set a key frame for 3D object position at zero and then I advanced the timeline to 3 seconds. With the roll 3D object tool selected, I edited the z axis orientation in the tool bar from 0 degrees to 360 degrees at the 3 second mark. I then played my animation and while the object spinned about the z axis, the position of the z axis was in the wrong place. the z axis was still aligned with the center of my extruded object if the depth had been set to the original depth of 1.0.
 
End result is it looks like my shallow depth hexagon is rotating about a point in space rather than rotating about the center of the object. Is there a way to reposition the axis so the center will be the center of the depth of my extruded object? In shots 1 and 2 you see the object with the correct depth but the wrong z axis location. In shots 3 and 4 the object has the wrong depth but rotates properly.
