About this 3D model

UPDATE 10/31/2014 - Now only two vertical bars are needed. - Still aligned with the extruder movement. - added 3 sizes of spool holders, and the source files so anybody can modify to other spool sizes. - the old files and pictures are available also. ............ Made to be as part of Prusa Mendel, using the same bars you used to build your printer and the bar_clamps from ( https://github.com/prusajr/PrusaMendel/ ). This is inspired from de PrusaMendel design and the new parts are derivated from the bar_clamp from the same model. You can download the STL files or the Rhinoceros file and modify as you like.
