Chain guide (Shimano derailleur)

thingiverse

Meant to dampen chain noise and decrease wear to both the drive chain and the derailleur, this piece was designed specifically to fit a 9-speed Shimano Deore rear derailleur. I'm not knowledgeable enough to state which models this will fit, but I can include the model it was designed for and hope that's enough to for you to determine whether or not it will fit you application. The piece fits on the metal guide on the back side of the derailleur between the tension gear and the guide gear with the flat side up as shown in the photos. PT1 is shown in the photos. PT2 is a slightly larger version with additional taper on each side. In testing PT1 was more quiet than the larger PT2, however; both are made available. Total print time is near 20 minutes.
