@brett I use SpaceMouse Wireless and it is great for both 2D and 3D navigation in #Fusion360, #SolidEdge, #OnShape, #PrusaSlicer, etc. It took me a couple of days to get used to it, of course. I like rotating the model and looking at it from all sides and angles, zooming in and out to check some corners, filets, etc.

Can you go without one? Yes, but it makes using these tools flawless and easier vs. with regular mouse. It works in many other apps, too, but its main strength is 3D navigation.
