Well I suspect the custom stuff that I'm going to design will be utilitarian in nature rather than artistic- replacement parts, organizational stuff, a little attachment to something, etc. So I'll want precise measuring tools. If I print something more artistic, I'll probably rely on models that already exist, like DnD minis or something.
In that case, I would recommend starting with FreeCAD (get a 1.0 release candidate from the weekly builds github) and make sure to watch a couple of intro tutorials. There are tons of CAD packages with pluses and minuses (and that's exaggerated in their free tiers), but if you can start with FreeCAD and have it as your baseline, you can avoid a lot of cost and annoying business practices, though as I mentioned elsewhere, Plasticity is not a bad choice if you go in knowing its limitations.
