Summary This is the design of an egg I made. 5mm section of the bottom is flat so it does not topple over. My advise is that you print this hollow with 3 shells and put a gift inside for someone. Once you give them the egg tell them to break it open and inside will be there gift. Chocolate, jewelry, etc. Enjoy! ( Rotate file 90 degrees along X Axis so the bottom of the egg is facing down. ) Scale up a bit too, the egg in the file is small.
