Compliant Hinge Example "Bookbind Hinge"

While working on my capstone project, I found that we needed a hinged part that, when closed, needed to have very few places for debris to enter the exposed front of the hinge.

I came up with this flexure hinge to print in the open position and close to a very predictable position.

I thought it was a fun flexure, and I can't find anything like it, so I wanted to name and share it!
