Easy Tools for 3D Printing

Hack Details: 3D Printing is cool, but the design and modeling tools can be difficult to use and hard to learn. So during the Hackday can we create tools in software and/or hardware which would allow a new user to just create 3D models in a more intuitive and interactive way.
What you need to make it happen?: 3D Printers. Interactive sensors and input devices. User interface, mobile application, game and general developers. Hardware hackers, electronic engineers.
