BB-8 Panel Nomenclature?

[kresty]

She's got 6 panels/sides.  What do we call them?  Here's my take.  I numbered them like a die (clockwise), just because it seemed arbitrary.

These are from the static model at the exhibition.  The rear/bottom-ish one there was hard to see, so I just marked the orientation of the tabs.  Panels 3 & 4 have tabs pointing directly at the closest panels (aligned with the seams).  The rest seem to be at 45 degrees to that, pointing at the triangular void between panels.
