This puzzle is a pyraminx that is designed to be faster than the current mass-produced pyraminx design. Using a GuHong type of mechanism, it allows for improved corner cutting and reverse corner cutting. Additionally, this puzzle does not have the "clicking" mechanism of the normal pyraminx, and is much less prone to popping.
Ordering this will only give you the plastic parts. You will also need screws, springs, and stickers to complete the puzzle. I used Type A screws and springs, and other sets may work as well, but this is the only set that I can guarantee will work on this puzzle. For stickers, the Cubesmith set of pyraminx stickers is not compatible with this puzzle due to its chamfered edges. Contact me if you need the sticker template to cut the stickers yourself, or alternatively, I can cut a set of stickers for you.
I understand that this puzzle is much more expensive that a mass produced pyraminx, but this is because due to the nature of 3d printing being much more expensive than injection molding. Additionally, the finish of the parts is not as smooth as that of mass produced puzzles, but again, this is the nature of the process.
