The rubber cover for the rear glass on the Porsche 996 Targa tends to degrade over time. This will fit as a replacement. You'll want to print in PETG or ABS to make sure it can handle the hot interior of the car sitting in the sun.
I printed it with a raft just to make sure that the 1st (top when installed) layer had a nice finish, since the masking tape on my print bed leaves some weird marks. I'll probably end up using some filler primer and a coat of matte black paint to make it look nicer.
