Sturdy Stacking Eggs

A set of 5 stacking eggs with a robust joining mechanism. Largest is about 90mm tall when assembled, smallest is 13mm. Took 83g of filament and printed using PS1, 2hr 27 min print. Tested in basic PLA.This is my first model created from scratch, so hope it is useful. The walls are deliberately thick as I wanted to emboss designs into them. Just haven't got around to it yet. I wanted a set of whale and dolphins. :)
