A replacement main-gear for the E3D titan extruder.
I ordered a part that I was not sure would really fit. After speaking to customer service rep she advised me that the part ordered will fit. I also when asked for another part, and she advised even though the manufacturer said it may fit she would not order it as she does not believe it will fit and I would probably end up returning it. This saved me a lot of time and frustration with something that may not have worked and I think that is awesome customer service. Thank You
