About this 3D model

Parametric OpenSCAD model of a nestable tube table, based on [Tested](http://tested.com)'s [*Jamie Hyneman On Welding in His Workshop* video](http://www.youtube.com/watch?v=EA1jeViV4l8&t=10m58s). Really simple, sturdy table which can be cut out of square steel tubes and welded together quickly. The latest code, examples and documentation is available at the [Git repository](https://github.com/l0b0/nestable-tube-table).
