My little child wanted some eggs to fill the basket we made from a kid magazine.
I modelled one in Blender. I started importing the svg shape of an egg that I found [here][1]

I sliced using [Cura][2], because [Slic3r][3] didn't give me as good support as I wanted.

I printed them (4 at a time) in PLA using my ReprapPro Huxley.
