Problem: Fredo Corner defaults all chamfers on 3d objects (two surfaces meeting at an edge) to a 45 degree angle. Anyone know how to change this to a 25 degree or what tool can be helpful for 3d objects.

For chamfer to work on corners with 3 edges or more (e.g. a true corner), the profile needs to be symmetrical.

If this is just to chamfer borders of a shape, then this is more a kind of followMe, and whether with the native tool or with Profile Builder by Whaat, you should make it with no difficulty.
