This is great! Everything printed out perfectly. It's a very clever design too, no supports required, the hinge works well, retention on the detents that hold the egg shell closed are spot on and the yoke clicks into the egg white and holds secure, no glue required! It is easy enough for my kid to open and close with out help and durable. My kid was rough with it and popped the shell out of the hinge. It clicked right back in with no damage done. You definitely earned a couple of boosts from me!
