Hi all,
as Mendel's X axis driving, with horizontal belt positioning, leads to belt wear and prints with a little ondulation into X side of printed parts, I made modifications to get a vertical belt positioning as Prusa Mendel or Mendel90.
You can find details, STL files and OpenSCAD models into this web page:
