I can't seem to find many videos about this but QiYi released an even bigger pyraminx and it is huge! It comes very slightly short of @matt.bahner Giant Pyraminx world record which he 3D printed. My solve time is terrible but I haven't found anyone faster yet, I do hope someone will solve it faster soon though as 21 seconds is absolutely not worthy of even being thought of as an unofficial world record. Turning is good and it even appears to be slightly magnetized, I think it got dropped at Stevenage and one of the magnets might have fallen out which may explain the weird sound inside when I pick it up. I don't have any current plans to sell this on my website as it would probably be around £150-200 but if anyone seriously wants one then contact me and I can get you one.
