Prusa i3 Idler X-End w/ built in fine tension adjustment. GT2 Belt. Drill and Glue to add to current X-ends.

Fixes the prusa i3 x-axis tension issues (if you have trouble getting the x-axis perfectly tight like myself) with a 605 bearing, bearing sled, and by adding a fine tension adjustment screw that pulls the sled toward the end of the axis.
