Bearing Holder

I have the Folger Tech RepRap Prusa i3 and upgraded to the
Achatz Dibond Aluminum Y-Carriage Plate.
the Zero Height LM8UU Bearing Holder didn't have enough clearance to pass though the frame with out reshaping the holes. So i created this Bearing Holder. I still had to trim a little from both sides to get it to slide. The Bearing sit on the Y-Carriage Plate and has a stop on one side. The nuts are also recessed and provide a near flush surface.
