The inspiration for this model comes from Yoshi/Pokémon eggs. The model has a special tray, which is used to connect or separate the spotted eggs.

I printed the models separately to save on consumables. The bottoms of the spots are flat and need to be bent. I gently bent them with my fingers until the spots matched the curve of the egg, and then I applied strong glue to them.

I use this egg to store Pokémon figurines, so I think it's a Pokémon egg.
