One of the things about "maker" is that in many ways it's a social descriptor - it almost means "someone who might read Make magazine". After all, it covers a huge variety of things. Someone who's into amateur electronics but is not a radio ham. Someone who dabbles in programming, does a bit of soldering, stitching, 3D printing, carpentry etc. Not someone who specialises in a particular craft. Also not an "artist" as traditionally construed (artist is itself a social descriptor), even though many of the pieces made could be considered art.
