Challenge your spatial awareness skills and then destress with the UGears Flexi-Cubus model — the kit that offers twice the fun in a small package. When assembled, it forms a mechanical cube puzzle constructed of eight joint-connected spheres that rotate into different configurations. Each piece is printed with a skeleton face in a steampunk design. It’s the perfect way to improve focus and keeps hands busy while brainstorming, meditating or attending school online.

This model is easy to put together using our unique pre-cut pieces that are made of a lightweight wood material, and it doesn’t require special tools or glue. Sustainability is important to us, so we use renewable resources for all our models.

The Flexi-Cubus kit contains 144 pieces and has a finished size of approximately 4 x 2 x 1 inches. The small size makes it easy to pop into a backpack or purse for engaging entertainment on the go. For a greater challenge and extended engineering time, assemble it without referring to the instructions. If you get stuck, the included PDF manual and YouTube video are ready to guide you through the process.

As any engineer knows, sometimes accidents happen, and replacement parts are available upon request. We’re happy to help get your model back in tip-top shape — just use the contact form on our website to ask us your questions.

Whether you want a quick brain teaser or an intricate mechanical puzzle, we have a model that’s right for your collection. Explore more UGears models and games in our online catalog, and check out our blog for more puzzle fun.
