Eg2-D2

This is a perfect model for Easter or for whenever you're having a boiled egg.

Note that I first had trouble with the bottom of the cup. At 5% cubic infill there was just nothing to put a bridge on and Slic3r didn't detect this. It just happily tried to print a bridge and the following layers in mid-air. Eventually it recovered but the purple print still has a little hole in the bottom.
For the pink one I changed to 10% rectilinear infill and looking the preview I made sure the bridge would be supported by the infill. This ensured a perfect bottom.

Time to print: ±3.5h
Slicer: Slic3r PE 1.41.3
