HERE, experiment with this new greeblin' compatible .LXF file.
EDIT: Added X-ray animation to better see the internal contruction.
Please excuse the non-symmetrical sloppiness of this draft (I got lazy).
Note: The non-connecting hinges, and 1x1 circular pieces are to help cover the visible plate gaps.
We all know LEGO Digital Draw gets anal with the exact distances between pieces, so even if these hinges don't connect on this digital plane doesn't mean they won't in a real life physical build.
Oh, and the structural integrity is not based on the connectivity of said hinges.
I stole the idea from Set #7661 Jedi Starfighter with Hyperdrive Booster Ring, and added a bit o' me own greeblin';)
