Fractal Vise Jaw Adapter

Fractal Vise Jaws Adaptive 3D-printable jaw inserts that conform to irregular and organic shapes Standard flat vise jaws struggle with anything that isn’t square or cylindrical. These fractal jaws solve that problem by using a nested, articulated set of segments that can independently shift and rotate. The result is a gripping surface that wraps around odd geometries instead of just pinching two points. How it works Each jaw is made of four nested fractal segments (Tiny → Small → Medium → Large). The segments slide and pivot relative to one another, allowing the contact surface to automatically adjust to the workpiece. A simple post-and-C-clip system locks the largest segment to the adapter block while still permitting full range of motion. Compatibility Designed as a drop-in replacement for common 4" and 6" machine vise soft jaws. The adapter block mounts using the standard hole pattern shown in the drawing. Printability - Fully optimized for standard FDM printers - No supports required on any of the fractal segments - Adapter block includes built-in break-away supports Assembly 1. Slide the fractals together in order: Tiny → Small → Medium → Large 2. Slide the Large segment onto the post on the Adapter Block 3. Secure with the C-clip
