Subject: Another {7,3} puzzle

I added a fun version of the {7,3} which has all three types of twisting.
The cuts are shallow, so the puzzle is relatively easy. The
vertex-centered and face-centered circles are all tangent to each other.
If the puzzle only had these two types of twists, there would only be
trivial tips to solve, and face turning twists would scramble nothing.
Adding edge-centered twisting makes things much more interesting.

With all the tangencies and mutual intersections, the pattern of cuts is
quite nice. A picture is
