Matt Bahner recently released a video showcasing his new 34x34 cube, this is incredibly impressive and is the highest-order cubic puzzle ever made. For the past few years, Matt Bahner has showcased his impressive 3D printing skills, creating some of the largest puzzles ever made. But he seems to have now improved his 3D printing skills to the extent that he has been able to design such an incredible puzzle.
The previous world record was the 33x33, created by Greg's puzzles back in 2018, unfortunately he remarked that it was a financial disaster for him as he never recouped the cost of the materials to make it.
It will be interesting to see how it goes with Matt Bahner and his 34x34, he plans to do further videos on the process that went into making it and has already done a speedrun through building it.
It is interesting that he has chosen to do a 34x34 and not a 35x35, building high order odd layered cubes is a lot easier usually as they have fixed centres and don't require inner pieces, but to be fair, I trust Matt Bahner most to know what he is doing with this, maybe he just wanted to challenge himself even more, or maybe there is something different about it when cubes get to this insane size.
He has chosen to make the puzzle have a stickerless design which I don't think we have seen before for any 20x20+ cube, he had 6 3D printers running, each printing a different colour for the puzzle, I can imagine this is the optimal way of doing things like that.
I am also impressed he has managed to keep any information about the fact he was building this from me.
