A geometric egg with a lattice for the shell.Must be rotated 180 deg to print on the flat base. Prints well standard size and at 195% with 0.15mm layers, 2 shells, and 15% infill.Note: In MakerWare the standard size takes 30+ min to slice. The larger 195% version takes well over an hour (i typically let it generate the path overnight). The print times are ~3.5 hours for the small one and 11.5 hours when printed at 195%. Both prints were done using a Replicator2.
