This is a remix of the original Surprising Egg (Prints Inside), and is is basically just an egg shell, which you can drop your surprises inside mid-print! You can then crack it open like a real egg.
I would recommend 0,8mm wall thickness (or two lines) as it's already quite tough to break (use a corner of a table or similar to break the egg). The egg has a built in support, which is easier to remove than slicers supports.
4 Different sizes, all with 0,2mm gap between the egg and the support.
Quail Egg 40mm
Chicken Egg 65mm
Swan Egg 120mm
Ostrich Egg 190mm
