Prusa MK3S/+ X-Carriage for Igus Drylin RJ4JP-01-08

I found a model with modifications to the original Prusa MK3 X-carriage and X-carriage-back to make Igus Drylin RJ4JP-01-08 bearings fit better, but couldn't find any version for the MK3S or MK3S+ carriages. I compared the .scad files from the file I'm remixing to the original MK3 files with the same rev. number, and made the needed changes to the current R7 parts for the MK3S/+. I also changed the rev. number printed on the parts to R7i, to distinguish them from normal R7 parts, and included the .scad files in case anyone needs to make minor changes for their specific setup.

Print with the same settings used for printing normal MK3S/+ parts, i.e. PETG with default 0.2mm settings.

NOTE: I had to modify the firmware to increase the homing currents to {15, 12, 20, 18} to get the printer to pass the belt test. This is still lower than the actual print currents so I don't see why this would cause any issues.
