Select the “loose” or “tight” version depending on how tightly you want the spheres rotating within each other.
To print, you will need to ensure that each separate sphere is properly supported. Tree supports work well, especially if you raise the object off the build plate 3mm or so.
There is a small cylindrical plug inside the innermost ball. This is to stop the supports from generating inside the innermost ball. It can simply be removed with the supports.
