Triquetra design 2

grabcad

Second attempt at designing a three-dimensional triquetra. With this design, the three vesicae piscis do form one contiguous loop but it's mostly completely flat, except for the three places where it passes over itself and has bends in it so as to facilitate that. Unfortunately, the inflection points where the loop bends to go around itself are pretty acute, and is completely flat everywhere else. As such, I'm not particularly happy with this design either.I'd like the bends in the loop which allow it to pass over itself to be gentler and also to bend the outward tips of the three vesicae piscis so that they envelop a perimeter circle, which was present in my first design but is missing from this one.
