Ball bearing nut for linear stepping motor.

I designed the ball bearing nut for the linear screw of linear stepping motor.
It is a kind of derivative of Mark Sollack's threadless ball screw concept.
This is one of the concept design to prevent backlash on the linear stepping motor.
I did not test yet. but I hope it would be work properly.
The ball bearing nut was designed for quadruple-start 8mm lead length, 8pi linear screw.
The slope angle is 17.6568 deg.
