The Marcato Tacapasta noodledryer is made of pretty bad plastic. It gets brittle and breaks after a couple of years. I have designed new triangular links, cut off the arms from the originals (foodsafety) and glued them into the new parts with epoxyglue. The original thumbscrew was replaced by a heated insert with a stainless M3x8 screw.
Works!
