Celtic Corner Braid -- Blender Script and STLs

This is another example of the 3D bezier curve elements that I am working on. This Thing is based on my customizable picture frame and my Blender python scripting to produce the Celtic Knots. Please see the "Derived From" links. STLs are provided for the final frame, and the corner braid element. I am posting the version of my Blender script that produced the 3D braids.
