This is a follow on to my prior Instructable about this idea. The Big and Small contest inspired me to share more about this invention, what it is, what it can do, and how I made the prototype parts. The relationship to size comes from the extreme scalability that this form allows. I have made the first prototypes from .030″ (.79mm) wire but I would estimate that this shape could be applied to wire from 1/2″ (13mm) down to .001″ (.03mm) this would be an estimated 500 fold difference in wire diameter that could be utilized. The micro scale would be envisioned for critical custom shapes such as surgical stents or micro prosthesis. The large dimensions would be applicable to buildings and bridges. What is small is the basic concept: A fastening technology based on one shape and one connection. What is big is the infinite array of shapes […]
