Months of trial, error, and relentless iteration went into turning a simple idea into a fully functional 3D-printed mechanical marble clock 🕰⚙️ What started as a clean concept quickly became a serious engineering challenge—tracks jammed, lifts failed, and entire sections had to be reprinted and hand-tuned just to fix timing issues. After countless revisions, the gravity system and lift finally work in sync, bringing the build to life piece by piece. Now the focus shifts to the marble selector—the most complex part—aiming to complete a project that turned frustration into precision and creativity. #technology #3dprinting
