I really liked the egg design and I had an idea to use it with some tiny creatures at my market booth.  They are really popular but I had issues with them fusing together if my filament wasn't perfect.  Not the original files fault, it was mine for making it to small.  Instead of making it larger again I made the outer shell slightly larger so that even with poor filament, the walls should not fuse together and you will have an awesome 3D Printed fidget toy and home for all your small creatures!

There should be a Print Profile for A Single egg, and another for a bed full of eggies.  I generally only do 4 at a time with a plate full of creatures and some single color fidgets.
