We saw a tweet one day where someone had done this, and wanted to try it. It's not as hard as it looks but very meticulous.
Two[*2] of the sides are 11x11, and one[*2] is 10x10, this is due to both the nature of its construction and an arbitrary design choice.
Since this cube is effectively three walls of rods pinning each other in, their respective surface areas are triaxially reflected; when beginning construction from the origin, one axis will "encapsulate" the other two, OR be encapsualted by the others. If one wishes for each face to remain congruent, then the opposite will be true of the axis of the terminating vertex. I chose to keep one[*2] of the sides smaller than the other two so that the reflected axis would remain encapsulated by its conpanions, thus it is not truely, in essence, a cube.
This is the origin corner. It actually might not have been lol but as we're about to see that doesn't really matter.
