Insert Fingerspin cho Magicyoyo N6

The Magicyoyo N6 is inexpensive, smooth, and small. But the flat hub face makes it difficult for me to fingerspin. This insert is simply pressed in place. Sand it smooth before you press it in. It also makes the yoyo heavier at 70 grams.

The two small holes allow you to screw a screw in and pull out the insert. 

Edit: I've done some experimenting with shapes and the finger hole size. I've added several files if you wish to experiment, but I prefer Number 12.
