5.2.2 Assembly instructions
There are some exceptionally detailed and well-writen descriptions about how to build a
standard Prusa RepRap. For the simplified version of the RepRap presented here, rather than
tell you exactly where to place each nut and bolt, figures are provided that should make it
apparent from the list of parts for that particular component. We have tried these build in-
structions out with several faculty and student builds, which were successful with only minor
supervision from experienced RepRap builders. You should be able to build the RepRap on
