Maybe a tangent, but I've gotten a lot of the joy back with 3D printing. You can just describe something, and Astra can model it in CAD extremely well. It usually takes a few iterations, and then you can just print it. I found that before, it would take days to build even simple models in Tinkercad - which while fun, was high enough friction that a lot of things would stay in the "ideas" folder - now I can have something real in an hour or two.
