Rocking knot

thingiverse

This unique knot has a distinct feature – it can only rest on a surface in two spots at most. This makes it easy to rock back and forth and roll down even shallow slopes. A fun addition to any desk, it also serves as an excellent beginner's 3D-printing gift. Both thick and thin versions of the files are provided.
