The Flexi-Cubus is a mechanical model, an octasphere puzzle in the form of a steampunk skeleton cube made up of eight interconnected spheres. This flexible connection allows the spheres to move and roll over each other, creating different geometric shapes. Each sphere is a mini mechanism consisting of six segments connected by a joint. The geometric model takes on the shapes of a rectangle and a 3D cube. The Flexi-Cubus is designed to enhance your focus and attention on the task you are currently working on.
