I too have been using FreeCAD for 3D printing. It's generally been going ok, but it can be difficult to achieve some complex things, the learning curve is steep and it's easy to forget the little tricks when you don't do it often enough. Several times I'll find I've spent hours building something and then it breaks and I have to start again, because of the relationship between features/parts and it just becomes impossible to resolve. It makes me jealous when I watch YT channels with people using Fusion360 making things with intuitive ease in the UI, it just seems much more straight forward to get things done. For anything I'm likely to reuse or modify I've started learning SCAD, since I write software for a living, the learning curve isn't as high, but you still need to learn the little tricks for doing certain things more easily.
