I live in the land of manufacturing and this stuff comes up all the time. A couple things to keep in mind regarding the part in question.
1. You aren’t manufacturing anything
2. You aren’t selling anything
3. You haven’t stolen anything, you scanned something and made the scan repeatable.
4. The imperfect scan you made can be printed but it is not the same as a molded part.
5. Because the piece has been scanned and 3d printed it is easily the necessary 10% different than the original part.
And most importantly the effort to reproduce this part as a hobbyist and make it look original is possibly more than it’s worth when compared to purchasing a licensed original reproduction and it’s value will never be that of a licensed reproduction.
That being said I would print one just to play with paint and finish ideas.
I am not a patent attorney but this stuff is pretty standard.
