A retro soviet puzzle game reinterpreted for 3D printing. The goal of the puzzle is to shuffle the cubes in such a way that on each side of the box, all of the four (4) visible faces of the small cubes have the same color. Small cubes can be moved by finger or by simply rotating the box.
I designed two kinds of frames, the cube frame and the cross frame. For a complete cube, you will need to print six (6) frame pieces and 14 cube halfs in two colors (7 halfs each). Glue the cube halfs and frame with very little super glue (see picture).
Glue 5 frame pieces, fill the cube as shown on pictures and glue the last frame piece in place to complete the cube.
From Wikipedia:
"There were two types of Minus Cubes manufactured: the so-called "Moscow Minus Cube" and "Sverdlovsk Minus Cube", each named after the cities in which they were produced. They differed only in the orientation of one of the small cubes (Marked with a star in the pictures). Because of this difference, there are 12 times as many "solved" arrangements for the Moscow Minus Cube, and thus the Sverdlovsk Minus Cube is 12 times as difficult to solve. However, if one does not confine oneself to these two types of the Minus Cube, there are 48 Minus Cube variants that can be solved."
Enjoy!
