The pen design "trinity" combines three models of a series of writing instruments in one ballpoint pen. The variants differ in diameter. These different diameters result from the possible usage types of the pen.
In my experiments, it turned out, for example, that a smaller diameter is better suited for precise drawing and a large diameter allows comfortable writing of longer texts. Changing the diameter of the ballpoint pen is achieved by reversing the protective cap of the pen and sliding a sleeve on the pen which is moved on the pen. Because the individual parts of the pen are force-fitted together, disassembly is easy at the end of the pen's lifespan and all materials can be returned to a recycling cycle. The concept is visualized with the help of digital renderings and 3D-printed functional models.
