Elvis has been improved! Check out "Elvis Skull Resurrected" at http://www.thingiverse.com/thing:158022
Thanks to "Cleaned Hollow Skull by ssd" for the mesh of the skull and mandible. I've cleaned up the interior a bit, attached the mandible, and added support and teeth. If anyone can further clean this up, please do.
Printable(?) because there are hanging filaments and a great deal of excess plastic on the inside that I haven't been able to lose. The drooping threads vary in quantity and placement depending on the scale. On the upside, the droops are all on the undersides or inside of the print, are easily cleaned up with an X-acto & sandpaper, and don't affect the final appearance.
The .stl file is at the maximum size that fits on my build platform. The other sizes shown were set at 75% and 50% scale in ReplicatorG and take considerably less time to print out. (The full sized Elvis took seven and a half hours to print with zero extra shells and 10% fill.)
Check out the sneer.
