Prusa i3 MK2.5 Igus RJ4JP-01-08 x-axis carriage R4

When upgrading my Prusa i3-Mk2, featuring Igus linear bearings, to the i3-Mk2.5S, I discovered that the Igus drylin were not properly secured in the new X-carriage frame. As a direct result, any movement along the X-axis produced an annoying squeaking sound. I utilized the bearing definition provided by @Noclafasm, which are exceptionally tight and well-designed, as well as the new x-carriage design, called R4, from Prusa, available at https://github.com/prusa3d/Original-Prusa-i3/blob/MK3S/Printed-Parts/SCAD/x-carriage.scad. I merely updated the reference to the bearing description and revised the STL by regenerating it.
