This is the absolute largest thing a Replicator 2 or Replicator 2X is capable of building but also contains minimum materials. You can use this as a tool to double check weather a part can be replicated or to demonstrate the Replicator's build volume. The actual build volume as stated on the site is incorrect as can be seen by a test in the makerware software, so this is the max of it's true dimensions of 24L x 14W x 15.5H in cm. This object needs to be scaled, so just hit maximize size in the scale menu. Also, since every makerbot's build plate are all centered slightly differently (especially the 2X) you may notice the extruder print off of your plate. In that case just uncheck the uniform scaling icon and drag in the side that seems to be overhanging by the amount your observed, and then you have your own custom print volume box. For printing use rafts and supports, I haven't tried without but I doubt it would go smoothly.
