A friend wanted to make customized breakable easter eggs so I got to work making this model.

Here is a break video showing how easily the eggs can be broken.

Specs:

- Printed on an Ender 3 V2. 
- Sliced with Cura 5.3.0 
- Low Quality (0.28mm) 
- No supports 

Surprise Easter Egg_Bigger Gaps.stl breaks easier but Surprise Easter Egg_Small Gaps.stl has a better finish.

You can place another model inside before slicing.
If doing so, I would recommend raising your internal model at least 0.2 mm above the inner surface of the egg and adding a custom support below it. 

I've included Meggi_07.stl as a sample surprise keyring that can be inserted.

Alternatively, you can drop in candy or other small toys before the upper portion is printed.

I haven't tested it at bigger sizes but it should be just as breakable if scaled up in your slicer.

Feel free to leave any makes or comments below and Happy printing!
