Rubik's Companion Cube

The Rubik's Companion Cube is an entertaining and safe puzzle based on Poh's Companion Cube and chapulina's Rubik's cube designs. It requires 35 pieces in total, including one core, eight corners, twelve edge outer pieces, twelve edge inner pieces, six center outer pieces, six center inner pieces, and six center core pieces. Instructions for assembly are derived from chapulina's Rubik's cube design, which can be found at thingiverse.com/thing:9913. However, the original instructions may not be available, so this rewritten guide will provide basic steps. To tighten the cube, you could try sanding a bit off the small end of the center core pieces, as the creator has done. Assembly consists of constructing six center assemblies, twelve edge assemblies, and attaching them to the core. The final step is to glue the last center assembly onto the core, locking the cube together. Remember to exercise care when twisting the cube to ensure all pieces are functioning properly, especially if the glue is not yet fully dried.
