These valances are infamous for crumbling due to questionable plastic used in their manufacture, and the ravages of heat and time. My van happened to have one more-or-less intact.
This does NOT include the screw holes, you'll have to drill them yourself. This is due to slight variations on different years of vans.
Made somewhat thicker (3mm vs 2.5mm on the original) for additional strength. Recommended you print it at 100% infill.
It's ~700mm long, so is a challenge to print in one piece.
ASA or ABS or PETG is a good idea for temperature resistance. PLA might work, but no promises for long term. Definitely paint it with something.
The author marked this model as their own original creation.
