this is a hinge i designed to fit on my MakerBot rep 2 in the mounting holes behind the front plate so i just drilled holes in the front plate to reach the holes that wherein the metal frame and cut a piece of acrylic for a front panel on a laser cutter. this hinge was made to be removable from the printer and easy put back on. i have not tested this to fit on the replicator 2x but i would be willing to bet that the holes for the frame are the same but you will need to look at the acrylic? and its spacingprint 2 of each and drill the holes in the acrilic and the front plate to fit
