Instead of the hood vent mesh and hood vent trim shown in the manual, I got no trim and rounded hood mesh. I don't see how I can make this work without it looking like crap. Since I don't have a trim piece to cover up my terrible attempt at cutting a straight line I am not sure how to go about this. Any recommendations for those with the same rounded mesh.

I have been looking for decent photos online but most are from the original design that included the trim piece.
