Hollow Surprise Egg

This is a surprise egg that is hollowed out. Put toys, candy, or anything else that can fit inside.

Print in place hinge, no supports necessary.
Once printed, use a scraper that is used to remove parts from the build plate or use something thin and pry open the middle of the egg. Once the middle is open and a little leverage is added, the lock should free itself and the egg should be openable. Be wary of using excessive force to open the egg.

Be careful of scaling down, may not open. Scaling up should work fine.

Suggestions for improvements are welcomed.
