Yeah. I teach this after school to 7th grade kids. Anyone can pick this up in a few hours.

They taught us to make Legobricks with CAD when I was in 6th. Wish I retained more of that and that it would be more widely taught.

I am reasonably confident that access to solid modeling and additive fabrication is now more widespread than ever.

I mean, like any other skill that has pretty much been my experience (though I tried fusion + openscad), but there is something about being able to ask a computer all the dumb noob questions that makes that first phase easier.
