Its a joy to have access to a laser cutter. :) This evening att Geekubator gave us some time to learn OpenSCAD and laser cut the creation with our laser cutter. Check it out and download the parametric file as well as a .dxf version from Thingiverse.com.
Most geeks dream of having their own laser cutter. With such a machine you can make the most intricate shapes in 2D and them cut them out on wood, carton, acrylic and other materials. Most commercial laser cutters are quite expensive but maybe Lasersaur will introduce some change in the future. Check out their project page here.
