These 3D-printable Easter eggs are designed to be fully customizable using hydro-dipping. With a size of approximately 95 mm in height and 70 mm in width, they offer a perfect canvas for unique, colorful designs. Whether you use them as decorations, secret containers, or for an Easter egg hunt, they provide a fun and creative experience for all ages.

The design consists of three parts: a hollow egg with a screw thread at the bottom (for both sealing and attaching the painting arm), a screw-on cap to close the egg, and a threaded arm that serves as a handle for dipping during customization.

How to Customize with Hydro-Dipping
Print as many eggs and caps as you like (white filament is recommended for easier painting).
- Print only one arm, as it will be reused for the painting process.
- Attach the arm to an egg by screwing it into the bottom thread, this will serve as a handle.
- Apply a primer spray to create a smooth surface for the paint.
- Prepare a container of water and spray different colors of paint onto the surface, creating a unique pattern.
- Dip the egg into the water using the arm, then remove it, the paint will transfer onto the surface.
- Let the eggs dry completely, once dry, the paint will be water-resistant and long-lasting.
- Unscrew the arm, insert small candies or messages, and close the egg with the screw-on cap.

This activity is fun, creative, and easy to do, even with kids! Once decorated, the eggs can be used as hidden surprises for an Easter egg hunt or as beautiful home decorations with a secret storage feature.
