I am 60 years old, female, and had no idea about 3D printing until 1 1/2 years ago. My son introduced me to this hobby, and although I didn’t believe I could do it at first, I love it.
I find it a bit difficult to design because I know little or nothing about Fusion 360, Blender and the like. Tinkercad works reasonably well.
So please don’t scold me if I do something wrong.
