Thingiverse

Thingiverse is a website in which users may upload 3D models into an online bank in which any person may download and use this model as they please. There is no cost, and it is all open source allowing changes or modifications. Thingiverse has the potential of making many human creations to be open to the public, without one company monopolizing on over-pricing items. Similar to that of Wikipedia, however with real, solid objects.
