Add a twist to this year's Easter Egg hunt by using 3d printed easter eggs. Unfortunately I lost the CAD files, so this instructable is to serve as an inspiration. If I have time, I may remake the CAD file and share it.
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
This is the inside of the egg. It is composed of three parts. The top shell, bottom shell, and a threaded rod. The two shells have threads on the inside in order to be connected by the threaded rood, which is hollow. The threads of one of the eggs should be smaller, so the rod should fit VERY firmly inside this shell. This will cause the rod to become permanently attached to one of the shells, so whenever you unscrew the egg, only one shell will unscrew each time.
Step 3: CAD/ Print/ Assemble
Design your Cad file, 3d print it and then assemble it. This take about 30 minutes to print with the Makerbot Replicator 2 and assembling it takes a few seconds.
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.
1. Make several eggs, each one bigger than the other, so you can make them into nesting "dolls"
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
