I can't recall what resources I used to improve with Fusion 360; there are a wealth of resources out there, I recall I did watch a few youtube vids on the subject. I'm not a complete stranger to CAD though, I've dabbled here and there for about 20 years or more, once I got a grip on the core workflow of Fusion it came together quite easily, and couple that with playing around with the various tools to see what works. There are times in the modelling flow that you may get a bit stuck due to the order of operations you have applied. Fusion keeps a timeline history of operations and it's somewhat possible to "refactor" it by moving things around - that can both fix things and also make your model break completely. So, I'd recommend looking up best practices for your model and history management. Also, don't expect to get your modelling right first time, or to be able to learn using your main project model, you can easily learn a lot using a bunch of test files to try things out, and apply those techniques to your project afterwards. With regards to using it for 3d printing - I don't recall again using any specific resources for this, but the main thing was figuring out tolerances and fit for parts. Again, use test models and print small test parts to see what works on your printer. Fusion's parameters can help here, as you can set up variables for tolerances/spacings and update them after the fact.
