I made this from a simple sphere. It was suppose to just be a simple alien, sci-fi spaceship. But everyone I show it too say it looks like the head or a helmet. While that was unexpected it does give a funny impression that the aliens are driving around in a giant head or helmet. I can see aliens stepping out of the ship with the same looking head.
I did 3d print it out and I printed it with no infill to save on time and filament.
