3D rotation - Cube

I'm probably jumping in the deep end here...
I can do normal 3D rotation. My current problem is trying to create a cube. There are six comps, one of which is the 'master'. Using expressions I can get the x and y to match up for the side pieces, the x, y, and z to match up for the back, and the top and bottom are giving me issues.
Thus far my efforts work only for two of the rotations, but since I want this to be spinning freely (it's meant to be hovering and rotating in the final design), I could do with getting all three working.
All six sides are 500px * 500px, with their anchor points at 250, 250, 250, meaning that I can use this as a common centre for all of them.
I imagine that there is some trick to achieving this, but at the moment it's escaped me.

The easiest way is to download the script, createCube, put the .jsx file in your AE script folder, then select the 6 sides, 6 layers in AE, and File>RunScript>Create Cube. Check the top box (it's French, yikes!), and it creates a cube from your layers (with expressions) with a null, so you can rotate that Null.

If you pre-compose all of your layers arranged in a cube, collapse transformations on the pre-comp and enable its 3D switch then you don't even need to use a null. You can just rotate the pre-comp in 3D.
