The instructions for building a RepRapPro Mendel 3D printer are supplied solely on a wiki. The problem with this approach is that the wiki is continually being updated as the machines are updated, however my machine that was purchased in July 2012 is essentially frozen in time.

To solve this I have converted the instructions to PDF format and archived them here (26MB, 140 pages). They are distributed under the GNU Free Documentation License, the same as the wiki-based version.
