+1 for Fusion 360, highy recommended for modeling hardsurface/technical pieces ment for manufacturing (even if you just 3d print them yourself).
Blender in terms of keyboards is most often used as rendering engine. In regards to modeling Blender is not recommended for technical pieces as you will be doing polygonal modeling here,
which is more suitable for anything redering rather than manufaturing.
However if you want to digitally sculpt organic shapes, for artisan cap masters for example, Blender would be an appropriate choice.
If you want to go into pcb design I would recommend easyEDA as I've made good experiences with this, but kiCad is also a popular choice here, and Autodesk Eagle while only offering a limited hobbyist license integrates vey well in Fusion 360.
