This little cut-out stage has sides the same size as the build volume of the MakerBot. Printing it out will give you a little stand-up stage illustrating the volume a MakerBot will print in, along with a reference of the extrude thickness.

A more sophisticated version of this file, with more text and some known printable and known unprintable shapes would be a valuable tool to people trying to get a sense of the power of the tool.

Print out, remembering to select "actual size" in your PDF printing utility, cut along solid lines, fold on dotted ones.
