Wind-Up Chick in Crackable Voronoi Egg – 3D Printed Easter Toy

A fun and interactive 3D print that combines mechanism + design. This model features a crackable Voronoi egg that opens to reveal a wind-up chick inside. Once out, simply turn the key and watch the chick walk. Designed to be visually satisfying and mechanically engaging, the egg breaks apart in a natural Voronoi pattern, making the “hatch” moment especially enjoyable.

Perfect as:

• Easter decor or gift
• Desk toy / fidget
• Conversation piece
• Kids-friendly mechanical toy

Assembly & Print Instructions

1. Print the Chick First
   • Print all chick components.
   • Assemble as shown in the model preview.
2. Install Wind-Up Mechanism
   • Insert the wind-up mechanism inside the chick body.  I bought my mechanism  from this link
   • Secure it using double-sided tape or a small amount of superglue.
   • Ensure the key is properly aligned and accessible from outside.
3. Egg Printing (Pause Step)
   • Start printing the Voronoi egg.
   • Use the pause-at-height feature (as indicated in the file).
   • When the print pauses, carefully place the assembled chick inside the egg.
4. Resume Print
   • Resume printing to complete the egg enclosure.
   • Ensure the chick is positioned properly before continuing.
   • NOTE: Remove the egg very carefully after the print plate has cooled. As the egg is very delicate! If you break it, don't worry! It's meant to be broken! HAHA
