Yeah, I thought of that. I doubt they use the same scaling factor each time though. I don't know whether they scale it randomly or by volume or what. Anyway, I think they might cotton on if they suddenly get lots of requests for very similar looking items . The part I had made was supposed to be 128mm long but it came back 230mm long! I've attached a photo of the real part and the RP part. The RP part is Grey because It's covered in primer at the moment.
