This is (hopefully, don't actually know) a strong version of Yet Another Fidget Infinity Cube V2. I noticed that whenever it broke it was almost always on the part of a hinge that goes in side one of the cubes. To fix this, I just made it so that both parts of the hinge go into the hinge instead of one going it to the hinge and one going into the cube. I think this might be a bit harder to print but I'm not 100% sure.
