Dynamic Spring in FreeCAD 1.1: Model a Clip That Actually Flexes!

#freecad #freecadtutorial In today's video, we will model all the parts of a clip from scratch, assemble them, and create a dynamic, flexible spring. You'll learn how to use expression variables to link the spring's flexion directly with the rotation angle of the clip. We will set rotation limits to prevent any part overlapping and ensure a realistic mechanism.
