I resized, split + solid base, and added a hole for an earring stud/wire. This was the closest shell I could find that resembled Ursulas.
The inside is hollow (less weight = less dropping earlobe). turn on supports!
Uploaded both full and split shell : installed new parts on my Ender, definitely not tuned well enough to print the non split model correctly. Good luck!
