Composite Link: 2_2_1 # 4_1
thingiverse
The composite link 2_21#_4_1 model exhibits a constant-radius tube tightened to its maximum potential. To observe the intricacies of crossing, a thinner version is provided. Conversely, a thicker variant displays the full scale. These knots, requiring minimal support material for printing, are made possible through RidgeRunner software. This program, available at http://www.jasoncantarella.com/wordpress/software/ridgerunner/, uses an algorithm to optimize length while preserving a tube around the knot. The shape, however, depends on the function being minimized; other minimization could yield alternative models. For further insight into tight knots, visit http://en.wikipedia.org/wiki/Ropelength, and for ropelength data, access http://www.jasoncantarella.com/wordpress/papers/.
