 This project started out as somewhat bizarre and frustrating for me. It remained somewhat frustrating throughout, but there's a sense of accomplishment as I managed to do math (!) and experiment with the tools I had more to create an at least moderately satisfactory result. I completed 3/6 of the diagrams. Perhaps later, I'll add the results of diagram #6 to this, though it's a little confusing as I wasn't sure whether the diagram notation was the radius, or was just an odd 0 and meant to indicate the borings should be 0.5 mm through the object itself (it should be the diameter, because eyeballing a 5mm radius makes the circle too large for the object). I also wasn't sure how to achieve the results of customizing the curves to have those gear teeth on the third step without it being messy and hacky. All the same, I learned in this assignment how to better use Sweep1 and Sweep2. This turned out mostly well, except for the part where it was difficult to fillet the cu...
