We were doing an egg drop and needed a solid egg that we could drop. We changed the base so we could stand it up, and we also added it to test the same drop each time. I printed mine with a 90% infill, so it took me a little under 5 hours to print. The great news is I have dropped it from 3 stories and it does very little damage to these eggs. Each egg with this setting took about 61cm3 of filament.
