All the parts for a Prusajr Mendel are in plate1 except for the PLA bushings. The bushings must be printed in PLA, the rest may be printed in either ABS or PLA. Printable in one go on a Mendel or similar-sized printer. The vertices have rafts between them so they can be stacked and separate cleanly. UPDATE UPDATE UPDATE: Improved parts, fixed errors, made all parts parametric. Source is at https://github.com/prusajr/PrusaMendel .Make sure that your printer has 200x200 active area.
