  • Retractable pen: How it works
      The retractable pen is a truly nice piece of engineering of our everyday life.

      As a tribute to that invention, I prepared an animated three-dimensional model of a retractable pen that visually explains the working principle of this mechanism. My video can be seen on YouTube.
      The 3D model can also be found on Sketchfab.
