UGears Flexi-Cubus

The Flexi-Cubus is a mechanical model, an octasphere puzzle in the form of a steampunk skeleton cube made out of eight joint-connected spheres. 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.

For extended puzzle play, put together this model without referring to the instructions. If you get stuck or lose the instruction book, the online PDF is always there to guide you to the next step.

Each of our puzzle kits contains pre-cut pieces for easy assembly without glue or special tools. The lightweight wood material has a smooth, natural feel. We use sustainable materials for all our products, so you can feel good about giving a gift that is safe for the planet as well as engaging for young minds. 

UGears is a startup established in 2014 in Kyiv, Ukraine. Little over 5 years later, the collection has grown to almost 90 models of gorgeous, intelligent design. UGears has invented and patented their very own plywood joint design. The unique self-propelled mechanical model kits are designed for self-assembly without glue and made entirely of high-grade eco-friendly wooden material. The models are fun to assemble as well as educational, and can also serve as decorative pieces due to their aesthetically pleasing design. Inspired by steam-punk fantasy, the clear view of all the moving components, including gears and pendulums, creates a unique, unforgettable and fascinating look at everyday (and not so everyday) machinery.
