Egg Wallet

This is kind if a modern version of the Fabergé eggs. It is small enough to hang it from a necklace a or attach it to a keyring. The egg is designed to store coins or - in an enlarged version - other objects like a car key.
The lower and the upper shell can get screwed together ( close left turn open right turn). An O-ring in the middle - printed in flexible PLA - ensures a waterproof sealing.
