Mendel90 is a design by Nophead that replaces many of the threaded rods and printed parts of the Prusa Mendel with flat sheets of MDF, Dibond, Acrylic or any other stiff sheet material. This simplifies construction, stiffens the frame, and always keeps the axes at 90 degree angles, hence the name.

I got my kit in early 2014, it took a few weeks to build but I’m proud with the quality of the printer, especially for the price. The kit came with a sample green PLA. First prints are bright green!
