Design It in Fusion 360

You can print other people's designs. You cannot yet make your own part that has to fit something real. You opened Fusion 360 once, found it dense, and closed it again. The thing that makes parametric CAD worth the steeper learning curve is not that it draws better shapes. It is that you design the recipe rather than the shape. You describe a sequence of operations, the software remembers it, and when you change a dimension near the beginning everything downstream rebuilds itself. That is the whole point, and it is what beginners miss when they model as though they are sculpting, produce something that looks right, and then discover that moving one hole means starting over. This book teaches the parts of Fusion that get you to a working part: sketches and the discipline of fully constraining them, the features that turn profiles into solids, the timeline that makes a model editable, and named parameters that let one number change six things at once. Then it covers what a 3D printer actually needs from a model, and how to measure a real object accurately enough to fit it. No engineering background required.
