I used fusion to design and printed ergonomic/partial prototypes on Prusa 3d printers. Then, I fortunately had a ton of manufacturing contacts because I have worked as somewhat of a production engineer before. Some parts were definitely difficult, especially the outer burr of the grinder (there were a couple viable ways to make it, but it is sometimes difficult to find a shop that is price competitive in say wire EDM machining and 5 axis CNC, or CNC and casting, so you have to get shops to coordinate with eachother) or the wood arch (because high volume wood shops are not nearly as technologically sophisticated as metalworking shops)
PCBway is a good option now, especially for 3D printed metal parts. They have CNC as well but they tend to struggle with anything that has complicated geometry or features. But 3D printing doesn't require approval, and for one offs is often cheaper.
