Does anyone know how to make a 6-color Rubik 3x3x3 cube as
an origami modular? I don’t. But I do know how to make 8/9ths of one.
But first, here’s how to make a modular 6-color Rubik 2x2x2
cube.
Thanks to David Mitchell for designing, and to Leyla Torres
for showing us, the Mondrian cube module. Her demo started by making valley
creases at x and at 1/2+x so that two opposite edges of a square meet. She
chose a main color scheme that was 4 squares each of 3 colors (paper squares of
solid colors, for example, or paper with color/white). My favorite color scheme
for a cube is 3 paper squares each of 4 colors, so that each face could have
all 4 colors.
To make a 6-color Rubik 2x2x2 cube, take x=1/4 (cupboard
folds), the same for all 12 squares, and 2 squares each of 6 colors, and make
Mondrian modules. The assembled cube has 4 sub-squares of each 6 colors, it
will be a Rubik cube, but will not be a “solved” Rubik cube.
It is an interesting mathematical question which, or whether,
one of the many ways to assemble this cube might be “solvable”.
To make (8/9ths of) a 6-color Rubik 3x3x3 cube modular, take
x=1/3, the same for all 12 squares, and 2 squares each of 6 colors. Make an
extra valley crease at x/2=1/6, then make Mondrian modules. The central
sub-squares
(1/9th) of each face of the assembled cube will be some combination of 2 to 4
of the 6 colors, but the other 8*6=48 sub-squares of the faces of the cube are
8 sub-squares of each 6 colors.
With a few modifications, one can make two of the mixed
central sub-squares to be only one color; then one has 50/54ths of a 6-color
Rubik 3x3x3 cube. Indeed, one can have two solid color faces. Choose 4 each of
squares colored {c1/c2, c3/c4, c5/c6}; and make the extra creases at x/2=1/6
mountain creases.
Thank you and have a great day!
