Replicator 2 Y-carriage

I've found the time to modify and make more stiff also the Y-carriage for my Replicator 2. It can accept the Igus Rj4jp-01-08 or the standard lm8uu. I modified the original drawing by VVilhelnn in order to have a thru hole instead the snap fits to keep the bearing in place. I also close the shape next to the rods to avoid bending and added a big chamfer around them. i didn't print them yet, but i'm pretty confident they are a great improvement!
