Dino 2 from http://www.thingiverse.com/thing:1912 shortened by 75%. My reason for doing this was that my Makergear hot end mounted on the Brutstruder http://www.thingiverse.com/thing:4036 no longer reached my build platform after I installed twotimes' z-rider http://www.thingiverse.com/thing:4740 and x-y lowrider http://www.thingiverse.com/thing:4213.Use 2 nuts and 2 M3 35mm or longer bolts to attach to the Brutstruder.
