You can use this machine to make door handles, dolls, cars, hooks...anything! This machine is called a reprap, and amazingly the specifications for the machine are completely open source, completely shareable and modifiable by anyone in the world. There is a worldwide community of volunteers working feverishly to support you and anyone else to troubleshoot and improve the machine. Most interesting of all, the reprap is ultimately designed to self replicate all of its parts, bringing us within tantalizing reach of a long envisioned era of self replicating machines."
