This
trefoil knot rolls around like an infinite rocking chair because it is "tritangentless", which means that it never touches a flat surface in more than two places at once.
To read more about how this knot was made and to download your own 3D-printable model, check out our Hacktastic article

This knot model has a wire diameter of 4mm and will be 3D printed in Versitile Plastic in your choice of color, with a numerical label corresponding to its place (3_1) in the
Rolfsen Knot Table.
