Rubik's Weighted Companion Cube

pinshape

A working companion cube assembles easily with six screws attaching center pieces to the core, allowing for adjustable tension on the pieces' movement. To build it, attach each layer from bottom to top, adding screws at each step. Once everything is tightened, middle hearts are glued in place to conceal the screws. An optional Aperture Science logo is included for manufacturer marking, typically placed on the white face. The center, faces, and corner print without support, but the edge and core will not print with proper support.
