One of the simplest ways is to use an  "ObjectContainer3D" and place
your visiable object inside this object container.

Steps:
1) Add an empty "ObjectContainer3D" to the scene
2) Then add your other object (sphere) inside this
"ObjectContainer3D".
3) To do "free rotation" only rotate one axis of each of these two
object.
4) Rotate the X axis of your inner object (sphere) and then rotate the
Y axis of the outer object "ObjectContainer3D".

Play around with the results. Try swapping which axis you rotate on
each object.

This should give you the free rotation you are looking for.
