This is a derivative of the Thing uploaded by Coldstone.

This thing is meant as an upgrade to the OEM, unsprung feeder parts used in older Flashforge Creators and in the CTC machines This is the spring armed feeder upgrade design first upload by whosawhatsis and redesigned over and over... In this design the lever arms can hold the fluted bearings used by these Rep1 clone makers. In this derivative I have separated the backplates that attach to the stepper motors so that the distance of the hot ends is not fixed and so the user can remove one motor for cleaning and servicing. i included the 2 peg files from Coldstones original upload.
