You can tweak the model shape through fusion360 by modifying its parameters.

Printing Information:

• Use regular supports to support the base of the egg or slice a little bit off the bottom for the same effect.
• There can be 2 ways of printing it:
  • If you have an MMU print it whole and assign the colors to the segments of your choice
  • If you don't have a mmu or want to waste less filaments print all segments appart and glue them together (if you want the default, check out my multipart remix of this model that makes this easier)
