This is the armrest latch for a MKIV Volkswagen. There are two stl files. One with the hinge posts separate and one with them attached. If you can generate easy to remove support, I recommend the file with the hinge posts attached. If not, I successfully printed the hinge posts separately and super glued them in.
Keep in mind that cars can get hot in the summer. Print this in a material that can stand up to the temperatures you normally see.
