Rotating rings toy w/ finger holds

I loved the original model, but I found that I liked holding the middle piece and spinning it with my other hand, while trying to rotate the axis so spread the other rings apart. So I thought of adding some finger holds to enable me to do that in a smoother way. 

So I made a hole through the center piece of the original one, and created a finger hold that you can simply insert into it (no glue needed). If you only insert one, it serves as a stand, but if you insert both you can spin it more easily! =)
