Egg-shaped box with a simple mechanical combination system based on shapes. It uses three rotating rings to lock and unlock the cap.

How It Works:

The safe is made of a base, three inner rings, three matching outer rings, and a cap. Each ring pair represents one step in the 3-shape combination.

Assembly Instructions:

• Each inner ring has a dot on one side — this side should face up when assembling.

• Each inner ring also has a notch — this defines the position of the shape that sets the combination for that ring.

  

• Pick your shape for each ring and place it in front of the notch.
• Snap the matching outer ring onto the inner one (they only fit together one way).
• Stack all three ring pairs on the base, aligned with the dot facing up.
• Once everything is stacked, press the cap on to close the safe.

• 

When scrambled, the egg stays locked. It can only be opened when the three shape combinations are realigned as set during assembly.
