This tricky egg has a hidden latch mechanism that will keep it securely closed until you twist a portion of the base.
Printing
All parts can be printed without supports.
Options
- Default Middle Shell - Sits flush with the egg surface. Use to keep the mechanism more hidden.
- Raised Middle Shell - Sits above the egg surface to make opening the egg easier.
- “Happy Easter” Middle Shell - Adds a holiday greeting around the middle of the shell.
- Spring and Bottom Shell with Bolt Hole - Use these with an M3 bolt instead of glue to attach the bottom shell to the spring.
Assembly
Assembly is the same as the original Twist Lock Trick Box. Watch this video for the complete process.
Make sure to pre-tension the spring
This will assure that the latches have a strong hold on the base.
Make sure to glue the spring peg to the bottom shell
If you do not fully secure these parts, the mechanism may become detached while in a locked state. I recommend using either super glue or 3D Gloop!, but hot glue can work as well.
