I was inspired to make this Golden Egg model based on an old cartoon I watched a million times as a kid; The Magic Trolls and the Troll Warriors.

Modeled and sculpted in Blender

I made it roughly 60mm tall - which is in line with a larger chicken egg. You can of course scale it up or down to fit your needs!
