How to attach a part to a spinning sphere?

[Vezonix]

I’m trying to attach a part using constraints to a sphere that will roll around but I don’t want the part to rotate with the sphere when it rolls around. I have tried welding and using align position but the part still rotates with the sphere.

The yellow sphere is the part I don’t want to rotate and the blue sphere is the sphere that will roll around.

This is what happens to the yellow sphere when the blue sphere rolls. The yellow sphere rotates with the blue sphere.

I have tried looking for solutions but couldn’t find any so any help would be nice

Found a solution by attaching a ball in socket constraint to the blue sphere from the yellow sphere and then putting the blue spheres attachment in the center of it self
