Telephonecord Puzzle

Telephone Cord Puzzle was made from discarded telephone cord from the Dutch
incumbent telco, which used it for testing toxicity of the different colours. All passed, by the way. The object is to screw the telephone cords together like a six-piece burr. This puzzle later evolved into Oskar's Spiral Burr.
