About this 3D model

One of those geometric snake things. I believe some people know it as Rubik's Twist. Properties: - Fully Printable in one go. - Functional hinges. - Clicks into 90 degree angles. - Rounded corners to have it go more smoothly. Took me 3 hours to print on the Makerbot Replicator. I've added the files for a 2 colour version using dual extrusion (named Black and White). This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/9snwCIbBetx
