Make it yourself

There will come a time in the very near future when if you need a part for something that broke, you'll just have to go to a local shop where they will use a 3D printer to 'print' you a replacement part.

Not long after that, you'll be putting one of these printers in your house to print replacement parts for things around the house. Some people will even use these printers to design and create new things in a way never before possible. Have an idea for a new thing-a-majig? If you can create a 3D model of it (easily done with free tools like Google SketchUp), you can 3D print it.
