Prusa X axis end brackets with flanged nut for TR8

Upgrade prusa I2 z axis with TR8 leadscrews. Reduce wobble on z axis. I used Eduardo Schoenknecht, model which I have only modified to use TR8 leadscrews. Also I don't like cantilever supported idle bearings so I added a support for the idle bearing. The bearings are held with 15mm internal retainer rings, you can also substitute with 5/8" retainer ring but it will be a struggle as you can see in the pictures.
