Da Vinci Perpetual Motion

This model has been tailored for 3D printing with no need for support materials through FDM additive manufacturing technology. The simplicity of the part split in the main body shells makes FDM ideal. A unique ball-running method is incorporated via the central 'axle', which can be adjusted in angle using a through M3 bolt for smoother movement, secured to the legs. The design was inspired by http://bit.ly/1EGRlrq and an axle update stl file is available separately.
