This entire tail tidy body is 3D printed. The threaded brass bosses that are inserted into the 3D printed body are extremely easy to strip out. I'm suspicious if the product will hold up long term.
Additionally the installation video shows the wrong hardware being used in one step. The hardware used in the video is too long and results in pulling a threaded boss out of the body of the tidy.
Be ready with glue of some sort to finish this installation.
