Quoting Loek Marcus
Nice work! But you've cut the BMW logo, and Nils' idea was to use this grille without cutting pieces. If you look good you'll spot it's just a 1x2 grille piece, non-cutted.
You're right but I just took the nils idea not his "way". Cutting this grille for me was a kind of adjustment done cuz I didn't have any other opportunity to reproduce in a better way the BMW logo!!! Ciao
