Editing 3D printing killer apps

{{777 notice}}

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.[https://www.academia.edu/13799962/Return_on_Investment_for_Open_Source_Hardware_Development][https://www.academia.edu/10143203/Quantifying_the_Value_of_Open_Source_Hard-ware_Development] 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. [https://www.academia.edu/4067796/Life-Cycle_Economic_Analysis_of_Distributed_Manufacturing_with_Open-Source_3-D_Printers] [http://www.mdpi.com/2227-7080/5/3/45]

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?
