Firstly, using only a ruler, I measured out the dimensions of the components as accurately as I could. The dimensions consisted of the width, length and depth of each piece. I began 3D modelling on Rhinoceros 7 whilst calculating these dimensions. I disassembled the pen and modelled each part individually prior to the merging and construction of the pen. I started off with the creation of the lower barrel as this was the easiest to model. I went on to creating the ink chamber which was similar to the lower barrel with additional spring holders. With the creation of the ballpoint tip, extra research into creating certain shapes was required. This was also the case for the creation of the spring. The cone and the helix were eventually discovered but transforming the helix into a 3D object remained a mystery. Luckily, online resources came in handy which helped towards figuring out the solution to this problem. With the rest of the components, they were trouble-free due to discovery of how to create the 3D helix as these were the most difficult areas to model.

This is the assembled paper ballpoint pen which was straightforward in terms of assembly. I combined and aligned each component with the center of each combining component which presented the 3D model displayed.

Although this project was challenging, it assisted towards the improvement of my knowledge of using Rhinoceros 7. The creation of the different components and watching it assemble perfectly together was what I really enjoyed. However, the final render still has room for improvement which is what I really did not enjoy. This was due to my ability level towards rendering. I plan to improve my knowledge towards rendering in terms of adding high quality shadows, reflections, environment and overall render quality. Reverse engineering surprised me due to how even miniature and simplistic objects can consists of a variety of different components.
