No, all parts considered to be Tetrix components are listed here.
Just out of curiosity, where did it come from?

It came from the tetrix resource set I believe.

That looks like the shims that come with the 8020 linear bearings. Do you happen to be using those this year, while the picture I attached shows a likely grey or black one, we had a bunch of white ones around and they come with the linear bearings.
