REVERSE ENGINEERED OBJECT: PROGRESS 2

I took what I worked on last week and added more to it this week. An issue I ran into during this week was my circles were set to radius instead of diameter causing my model to come out wider than intended. To make the pen I measured the size and turned them into 2D shapes. I then extruded the 2D shapes to the right length. doing the same process with the inside of the shapes and then using the boolean difference tool to cut out the excess in the shapes.
