Summary After seeing how much the original setup vibrates during printing. I made a version of this for my Spring loaded exstruder. Its made a big difference on the quality of the prints, i no longer get a seam on small sylinders and items generally come out much much smoother. There are now 2 versions of this, one with the cables coming in in front and one that is structured to receive the cable feed in the back. Instructions THis only works together with the spring loaded ekstruder, you have to download the side holders from extra Bendit-ed 12 mm guide rod for leapfrog creatr. http://www.thingiverse.com/thing:209408
