Digitized Mechanisms -- Let's Write!

In the fall semester of the academic year 2019-2020, I was tasked with digitally recreating a real-life object using computer aided design (CAD) tools and making technical drawings for 3 parts in addition to an assembly drawing. Although everyone had to do this, I felt it pertinent to include as I had chosen a particularly complex object to model. Due to the fact that the object you chose must eventually be modelled in its entirely, many chose to pick simpler objects, such as a small chest or a door hinge, and rightly so. However, as I had already taken a college class in CAD design, as well as extensive experience through my own hobby projects, I decided to challenge my skills by picking a more difficult object.

I decided to recreate a Zebra Sarasa 0.7 mm Gel Pen, which is my general go-to pen. I chose it due to its complexity in shape, the pleasing design, and the opportunity to understand the internal mechanism. Although not required, the final CAD model has a fully functioning clicking mechanism, with proper mates and collisions.

The following is the actual pen it was modelled after.

The following is the full finished renders after all measurements were taken and modelled digitally.

The following are the created technical drawings associated with the above three parts, as well as a final assembly drawing.
