Cool Sphere

This is a cool sphere I made by rotating 9 rings. This shape probably has a real name, but i have no idea what that might be, so please tell me if you know. It has 2 add-ons, both accessible through Customizer:
1. Hanging Decoration - This add-on adds a loop to the top to be hung as a decoration.
2. Cat Toy - This add-on adds a sphere in the center to function as a cat toy

I hope you enjoy printing this design!
