Screw Fit Puzzle

Screw Fit is a packing problem. Four colorful helical pieces need to be fitted inside a nut. The nut has multiple threads with different speeds. Moreover, two are lefthanded and two righthanded. Each of the four colorful pieces slides through a different thread. The packing problem is designed to have a unique solution, but many near misses. Once the solver knows where to place the pieces, the next challenge is to slide them in together, using coordinated motion and a bit of dexterity.
