3 Jaw Chuck with Planetary Gear System

In this project, I designed and built a functional 3-jaw chuck that uses a planetary gear system to achieve synchronized motion of all three jaws. This mechanism provides a compact, efficient, and elegant way to grip cylindrical or symmetrical objects — all made with a standard 3D printer.

It's ideal for educational demonstrations, light-duty gripping tasks, robotics, and hobby CNC machines.

It can be easily controlled via a Stepper motor (NEMA 17 in this case).
