Your eggs are great. I think the knitted one is the best. The flora egg will not slice properly in Simplify3D. On the bottom, it doesn't print for the first 7 layers. At the top, it doesn't close like shown in your photos. There's something about the geometry that's just not quite right. I've tried the repair choices in Simplify3D, but it doesn't help (it does identify self-intersecting surfaces both at the top and at the bottom of the model). Do you have any idea what's happening?
