Not sure how old you are Dzl, but it is rarely too late to start learning. I have a 3D printer less than one year. The design software I use is Fusion 360, free for home/non business use. Previously my 3D CAD skills were limited to cylinders and cutting holes in existing designs, but after a year of messing around with the program, I can do many things that i couldn't do before. Don't be afraid to dive in.I am bitterly jealous of 3 groups of people here:
1. Y'all with 3D printers
2. Y'all with the skills to program shit to do make it do what you want
3. Y'all with a deep understanding of the fundamentals of electricity
?
"Fundamentals of electricity" was literally the name of my first college electrical class, a 6 credit hour class that i took when I realized that in my job a good understanding of electricity would help me. So I went back to school at age 26. I remember worrying that the younger students would be far ahead of me but not so, as life experience helped me more than I would have guessed. Get you a meter and a beginner kit of some sort and get your feet wet. Nothing beats hands on learning and burning up a few things.
