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!

Yes

I printed mine with a raft (may not be necessary) and support touching the bed. I do not recommend generating support everywhere (interior) if it can be avoided. I was successfully able to remove all the support when it was generated only touching the bed, even with the sphere printed inside (CatToy-2 was tested).

The sphere is created by rotating 3 rings in the XYZ planes, and then rotating 3 of those groups 45 degrees apart. First, I used OpenScad to generate a ring using rotate_extrude() and circle(). I then used two for() loops for the rotation. One was for the rotation of the XYZ plane, and the other was for rotating the groups 45 degrees apart.
