The online community of MakerBot Industries is called Thingiverse. This open-source community is a place for developers and innovators to share their digital designs with the world. Thingiverse believes that just as computing shifted away from the mainframe into the personal computer that you use today, digital fabrication will share the same path. In fact, it is already happening: laser cutters, cnc machines, 3D printers, and even automated paper cutters are all getting cheaper by the day. These machines are useful for a huge variety of things, but you need to supply them with a digital design in order to get anything useful out of them. Thingiverse is hoping that together they can create a community of people who create and share designs freely, so that all can benefit from them.
Because Thingiverse is an open source community they ask of you that you upload the source files for your 3D designs as well as the rendered output. This way other people can exactly see how the object is made and possibly add enhancements to the early model, which is the entire idea of this open source community.
Currently in their collection and open for improvement:
Thingiverse is ahead of its time with their open source model. The theory that open source communities are going to drive the development in the additive manufacturing industry is already widely adopted by specialists in the field. So if you want to take a look into the future, take a look at Thingiverse.
