Inspired by the spool holder angle that @ultiarjan designed and uses https://www.youmagine.com/designs/ultimaker2-rail-system-u2rsI had 3 shafts banana from my ultimakers so I did this to recycle them.Tips:- Print the D2 file mirroed for the other side of the machine.- The other files, just onceThe D1 fits inside the D2 but isn't a bad idea to glue them once you short the distance.The small bearing containers of the D1 file can be screw to the long part with some 25 m3 screws.I did all this in a rush, for me works, but fell free to change anythingSTEP FILES INCLUDED, change anything, go bananas :D
