About this 3D model

This is a model of the prime knot 8_2. It is tied in a tube of constant radius, and pulled tight. In the thin version, the tube has been reduced to half-size in order to help you see the crossings. In the thick version, the tube appears at full scale. These are easier to print without as much support material. For more information about this prime knot, look at its page in the *Knot Atlas* http://katlas.math.toronto.edu/wiki/8_2. For more information about tight knots, see http://en.wikipedia.org/wiki/Ropelength. For ropelength data, see http://www.jasoncantarella.com/wordpress/papers/.
