Prusa Mendel Documentation

A new reprap printer will built along the lines of the Prusa Mendel. You can find details of the Prusa design at the Prusa Mendel page on the reprap wiki, or you can view the sources for the Prusa at github

Intro

Having another 3d printer in the space will allow us to always have a working machine and to use one machine to help fix another if there are problems. It will also enable several people to print things out at the same time. The goal is to document this build so others can make their own printer following our documentation.
