In mathematics a torus is defined as a geometric shape created by revolving a circle in three dimensional space about an axis coplanar with the circle. Some examples of objects with torus-like shapes are doughnuts and inner tubes. Torus shapes can be deformed into "knots", that is closed, intertwined geometric forms with no beginning or end. This colorful papercraft torus knot is the work of Matthias Baas of Germany. The knot's template is interesting in that it is designed to be printed double sided so that the printed fold lines all occur on the inside of the model. The PDF template for the knot is located here.
