I'm very curious how you will do your eggs so I would be very happy to see some photos!
My family Easter tradition is to paint eggs.
Of course you can just print in wanted colors.
Print a few a of these different flat infill eggs and combine which one you want to create an ornament.
Put them outside in your trees or just inside for your Easter decorations.
Normal egg: 45.9 x 60.64 x 4.04
Big egg 270% of normal: 129.93 x 163.73 x 10.9
I've uploaded a few infill pattern but you can choose another one or change the density for your needs.
