This is created for a ball, inside a ball to make the movement of the outside separate form the inside the gyroscopic mid ball bearing weel couplet part is between them. picture a ball bearing it has the balls on the inside foe the outer weel and inside the inner weel. that means the inside has been created to spin, were as the outside will spin in the opposite direction. the able can spin in any direction, at one point. this is useless unless you build it form the inside out form the middle to the center of the middle. a ball must be constructed towards the bearings measurements foe the actual balls. the plate created to hold the ball in the mid of the plate will correctly configure a gyroscopic "sphere" bearing. I repeat the ball on the inside and outside must be smooth, on outside of the middle ball, and the inside of the outer ball.
this could be used as a gyroscopic holding divice.
