Composite Link: 2_2_1 # 5_1 (left-handed and right-handed versions)

This is a model of the composite link 2_21#_5_1. Since the Hopf link 2_2_1 can be positive or negative, and the knot 5_1 comes in left and right-handed versions, there are two topologically different versions of this link. Both versions are included here.

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.
