Description
Meet the Mini Claw Machine, a tiny 3D printed claw toy designed to be built in just two pieces: the main structure with the claws and internal spring, plus the rod that connects everything and makes it work. Once assembled, simply push the rod toward the body and the spring inside will open the claws automatically. The rod includes a small ring, so you can hang it wherever you want and carry it as a fun everyday keychain. Lightweight, compact, and satisfying to use, it is a playful mini mechanism with a clever opening action.
