EDIT: I have remade the file, but I have tested it yet. Unfortunately, I don't have time to go to techshop to get it printed. Try out the file at your own risk because I cannot guarantee it works. Feel free to make changes to it.
Step 1: Ingredients
Step 2: Humpty Dumpty Had a Great Fall
Step 3: CAD/ Print/ Assemble
I have attached a stl file to use, but I cannot guarantee it works. The Easter egg may not fit together properly, so try it at your own risk. Feel free to make changes to the file. If you decide to go ahead and try out the file, let me know how it works. Click "Easter Egg-untested.stl" to download the file.
Step 4: Other Eggcellent Ideas.
2. Add threads directly onto the egg instead of using a 3-d printed threaded rod. This will create a more spherical volume inside the egg instead of a cylindrical volume.
3. 3D print a Easter basket to use with the eggs.
4. Fill the eggs with candy and hide them
Step 5: Questions?
