47. Have you ever had a key made?

You currently go to the hardware store. There they have a lot of blanks for various cars or locks laying about. You select the appropriate blank and then cut it to fit your need. The thing is that plenty of those blanks never get used. They're just kept around in case someone needs a key. An easy use of 3-d printing is to make the pieces as they are needed rather than having a few hundred blanks in every hardware store in the world.

Now if it gets so that they can make really strong and elaborate products, you could have parts like replacement clutches or transmissions available. Even with just plastics, if you need a rear-view mirror for a 66 mustang, they could create it.
