This flexible connection allows the spheres to move and roll over one another creating different geometrical shapes. Each sphere is a mini-mechanism comprising six segments connected with a hinged joint. The geometrical model takes the shapes of a rectangle and a 3D cube transforming by bending the joints from one to the other and back as many times as you want. The Flexi-Cubus is designed as a means to improve your attention and focus on a task you are working on. It will help you to relieve anxiety and stress, and direct your thoughts and feelings in a positive way. Ugears has created this 3D puzzle with great care and perfection. It is made of attractive, high quality wooden material. All parts are pre-cut into plywood boards and are easily removed for assembly.
