Prime Link: 7_3_1

This is a model of the prime link 7_3_1. 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 link, look at its page in the Knot Atlas
