Replicator 2 X-carriage

I re-design the X-carriage for my Replicator 2 because the original one is not enough stable and i wanted to try the Igus Rj4jp-01-08. I modified the original drawing by VVilhelnn in order to have a thru hole instead the snap fits. I lowered 2mm also the belt locking system. In this way the x axis it's a lot better...i'll work also for the y-carriages as soon as i'll have the time to do it.
