This is a single vent for my 1993 Volvo 240 rear deck. The original vents are 2 pieces, each with 4 vent holes each; this was simpler so you just need to print 8 of them and push them into place.

I just made some shapes and some negatives and recreated a single vent instead of trying to make all 4 connect.
