Geeetech Prusa i3 Pro B Z axis anti-wobble

Tried the other z axis anti-wobble and they didn't fit like I felt they should. I made the nut end tall enough so the z axis linear bearings did not sit on top of the fingers. I also did not recess the nut into the bottom since I wanted to make sure the mating surface was as flat as possible. My printer had problems with creating a level and smooth recessed bottom surface. My prints have improved since I installed this part.
