After one of my BiC pens cracked, I decided to build a new pen instead of buying one; not a smart choice speaking from an economic or time management perspective. I only needed to build a new pen casing since the pen cartridge was still intact. I also decided to build a new cap aswell. I designed the pieces in Autodesk Inventor and then printed them off at my local makerspace. Looks like the results aren't half bad.
