Fixing the Marble Machine Clock

Building a Giant Clock That Tells Time with Marbles

Saqi | AI Robotics Creator on Instagram: "What happens when gravity, precision engineering, and 3D printing meet? This project explores the creation of a fully functional marble clock built entirely from 3D-printed components. Over months of iteration, the creator faced mechanical failures such as jammed tracks, misaligned lifts, and timing inaccuracies—each demanding redesign and manual refinement. The final system relies on controlled gravity circuits and synchronized lift mechanisms to measur
