The designing is involved to be sure, but it’s the actual hands-on experience of making a physical object that’s the fun part to me and with 3d printing and CNC that’s pretty hands-off by design. There’s some fine tuning, tinkering, and adjusting to do to the machines to be sure, but once the design is set and you have the machine dialed in, you’re mostly just letting the machine run and keeping an eye on it in case it starts making spaghetti.
I’d rather be the reason its accidentally making spaghetti.
