It's just an egg, but it has a surprise inside, and can be cracked open to reveal the content in an original and alternative way to give someone a present. Start the print, pause it (around 130 layers in, it already should have a pause in the sliced file), put the surprise inside, and finish the print.
Features No seams or mechanisms, the content is completely sealed inside Put anything you want inside. The diameter for regular is around 4cm, for medium 5cm. Original gift. Very simple yet original idea to surprise someone Beutifully simple It looks like an egg It's not an egg
Tips It's just one layer thick so it should be easy to open. In case just do the opposite of what's generally soggested to get strong layer adhesion.
If you scale it up, consider that the wall will scale up too and will get harder to break, use the bigger version.
Keep the print pause short to keep the seam invisible. Needs arachne active. Tested in pla.
