The egg is printed in one continuous operation without supports and build plate adhesion is achieved with only a brim.
As the contact area between the eggs base and build plate is relatively small there is the potential for the egg to move, detach and fall over.
However, in order to prevent this happening once the first spiral starts to form start to incrementally reduce the build plate temperature from the set temperature to room temperature over several minutes.
Additionally, print speed is reduced to improve the quality.

Post processing is required once the print is complete.
This will be required to remove excessive filament between the spiral gap.
First start with a sharp blade to remove the larger pieces, than a file and sanding paper to smooth the surfaces.
You can finish with a number of different methods to suit, solvent, paint, polish or epoxy etc.
Further experimentation will be required with infill type, temperature and/or print speed combinations that minimises the degree of post processing.
