About this 3D model
Another idea using models created by the [Flexy-Frame Construction Kit](http://www.thingiverse.com/thing:260226). Print as many as you want and combine together with the three lobed connecting pieces. This could be printed pre-assembled with dual extrusion. One flexible and one rigid filament. Other tessellation shapes can easily be created with the construction kit too. http://www.gyrobot.co.uk http://www.facebook.com/gyrobotuk
