MK2 Y-Axis Linear Rail 10mm round bars

Remix of https://www.printables.com/model/31768 Drop-in replacement for Y-Axis corners on MK2 and MK2S that allow linear rails to be used instead of the linear rods. Increased height by a few mm and enlarged the 2x 8mm holes to 10mm holes for the cross-brace bars. recommend using 9mm linear rails. 12mm can be used also but the tolerence would need to be adjusted or you would need to file away a small amount of the inside of the wings.
