Yoshi Egg container created as a gift box for my son's birthday party.  I couldn't find any that was thin enough to create multiple ones and not use up all my filament.  The white shell is 3mm thick and the color shells are 2mm thick. The top snaps onto the bottom portion and just a light squeeze of the shell pops it back off.  Large enough to fill  with candy and a few 3D printed trinkets. 

Will need glue to assemble. Print with supports.
