We know from this class that 3-D printers can be incredibly useful tools for prototyping and direct digital manufacturing for engineers and scientists. The costs savings are generally 90-99% as compared to commercial products.[1][2] Are 3-D printers useful for everyday consumers?

A few Michigan Tech studies have shown that 3-D printers are cost effective for consumers if they print 1 product a week. [3] [4]

What about killer applications? Are there free 3-D printable designs for products that make a 3-D printer immediately worth purchasing even if only to print out a handful of these products?
