Here are some files generated with "Egg-O-Matic". I'll keep posting new files here as they are generated.
The great thing is you can make MULTI-COLORED eggs on any printer. For example, to make 2 color eggs, you would print the SAME stl file 2 times, once in each color. Swap the pieces around and you'll have enough to make 2 eggs in 2 colors. You can swap the pieces around a lot of different ways depending on the number of cuts.
