I recently got a MakerBot Replicator 2 skeleton. The replicator frame came only with the Z-axis no X or Y carriage or parts, no electronics nor cables. Here are the Y axis brackets. I like the snap-in design from the original replicator 2, it makes it easier to work on the machine. The snap-in functionality needs PETG or ABS (needs flexibility), I have included both version snap-in and solid versions. If using PLA use the solid parts.
