The word "one-faced" in your question makes it a little more complecated to answer, but there are "multi wrap-around styles" dials. At first I thought of a star dial or cross dial or complecated baroque dials, but they are "multi-faced" dials and not "one-faced" dials. In the same body there are many styles and also many planes. But an example that would be as defined is the half of a hollow cylinder, with axis parallel to the earth axis. The two edges act as a polestyle, one for the morning and the other for the afternoon hours. To be honest, this isn't a plane dial but a cylidrical dial, however, still with one face. I have no examples of a dial with a 3 or 5 or .. 'sided gnomon'. Best wishes, Fer.
