The hand squeezer

Greetings! This is my second submission for the Casabella "stringmop" competition. While the core concept remains the same as my first entry, I've made some modifications - placing the pulley mechanism at arm height and altering the spring contraction method by rotating an upper handle. I believe this mechanical principle has immense potential due to its novelty and unique approach. However, it requires further work to enhance manufacturability. A straight shape can replace the helix for increased manufacturability without significantly impacting performance. Your thoughts are appreciated! Best regards, mcluka
