Pentacle Pentagram Puzzle comes from Yukang Wu. The internal mechanism is a 3x3. However, there are no edges.
Also, in order to turn the puzzle, the circles have to be lined up along one of the lines.
Scrambling and solving this puzzle is slow going! You may turn the top face once, but every turn thereafter requires constant orienting of the circles.
So far, I've solved it once.
This puzzle is extremely well made. I got mine for about $15 on ebay. Search Pentacle Pentagram.
