I'm sure there are a few ways to do it. I originally planned to print a new camera bezel and mount, but decided to go this route in the interest of time. Even in person you can't tell it's not a factory piece, so I'm pleased with the result. Thanks for subscribing!Nicely done, subscribed! You can barely even tell there's been a modification. Maybe a YouTube giveaway for the OEM grille?
Instead of cutting the factory camera mount thing, I think I would've used a moldable putty like Sugru or something to get the shape of the camera mount, cut away the centre bar from the aftermarket grille and adjusted the mount's dimensions in CAD to fit in the space. Also print the centre bar in to the same piece so it's all one.
