Prime Knot: 8_9

This is a model of the prime knot 8_9. 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*
