3D printer. I've had one for a few months, and in that time I've made at least half a dozen replacement parts for things around the house, not to mention a lot of other things I've printed just for fun. Example: grommets for the hanger wire on a bird feeder. The old ones were worn out, and it kept falling down and spilling the seed. It was a very simple thing to CAD up and print, but meant that I didn't have to buy a whole new bird feeder.
