I was asked by one of Patreons (Louis Warnell) to create a how-to video on changing my designs within Fusion360. I take the simple dual controls part and show you how to edit and change the diameters of some of the parts to help you create customised parts for your project. Let me know if this is of any use, too slow or too fast, not enough detail etc. Im thinking about created dedicated small how to videos for different things on the website.
On a further note, Fusion is still free to hobbyists and you do not need to pay for it! (Yet).
If it's asking you for subscription fees, you have not selected the right options as a private hobbyist. For commercial purposes, you need to pay.
