Yoyo Design

This design isn’t very complicated due to the fact that i don’t have very high tech programming (i used microsoft paint lol) You might have to zoom in the light grey in the middle is the bearing
is this to much like the evil yo? if it doesnt look 3d think of the 2 ovals as cylinders
p.s. im not sure if this is in the right forum please tell me if it is thanks
