This clip was modelled for a Mercedes Sprinter rear door card/trim clip (green ones) that i lost. I think this is used on lots of other car makes and models.

Its probably better to buy the original clips as they aren't expensive but if you just need one in a hurry these work well and only take a few minutes to print.

I've printed in PETG to survive the heat in the vehicle but other high temp filament will also work. Printed with support which is a little fiddly to remove but sadly required.
