My wife needed a way to safely transport an egg to work, for lunch. I used this as an excuse to test a grip texture pattern I was working on. The cradle has some spring to it, which allows a small range of egg sizes. These are sized to fit large eggs, although I see no reason why the design couldn't easily be scaled up or down. I should point out, the egg goes in pointy side down, as in upside down from how they would be placed in a normal egg carton. Enjoy!
Print both the Base and the Lid with the flats down on the bed. Print the Cradle flat on the bed, as well.
