15阶五魔 —— 世界最大魔方诞生

祭司zhangcy

I present the yottaminx. It's a 2kg, 7 layer face turning dodecahedron with 2943 functioning parts. It's the highest order twisty puzzle ever created. The inspiration for building this came when I felt a strange calling to build something massive. There really was no reason except I felt it was time. Back when I first started cubing, I would always joke about the existence of a yottaminx. I still cant believe it's real when I look at it.

I owe a big shoutout to Oskar for mentoring me through the designing of this. I settled on using floating anchor mechanism. It's very space efficient, making printing cheap (hahaha), and it's incredibly stable. The only problem I have with this is that some of the pieces rotate in place. It's really only the shorter ones that do it. If the anchors were angled more, I'm sure this wouldn't be an issue. Stability and friction aren't issues at all, making this mechanism viable for even bigger puzzles.

I had this finished about a month ago, but as I was tensioning it, one screw wasn't moving. I pushed really hard with my screw driver, and as a result, the world's largest twisty puzzle had the world's largest pop. It took a long time to fix, but I did.

Next year I'll be off to college. Hopefully my university will have a 3D printer I can use for puzzles. In that case, this is just the beginning. I think that the limits of big cubes are only limited by imagination.
