Locking Sphere
thingiverse
This is a basic locking mechanism consisting of two interlocking spheres. Simply align the two parts, then turn them until they securely click into place. I recently revised the design to include a deeper twist lock, a flat base for stability, and a small fill hole. This modification allows the sphere to be filled with materials such as chalk or shot.
