The Flexi-Cubus is a mechanical model, an octasphere puzzle made out of eight joint-connected spheres. Each sphere is a mini-mechanism comprising six segments connected with a hinged joint. This flexible connection allows the spheres to move and roll over one another creating different geometrical shapes.
Build the cube, then discover how each segment works together to shift the overall shape.
UGears models are made from laser cut high quality plywoods. All the gears and mechanisms are designed to snap together without needing additional tools or glue.
Note: It’s helpful to have a craft knife handy in case pieces do not release easily from the surrounding wood.
