I am 65, and retired, living in Franklin, KY. I have two home hobby shops, one for wood, the other for metal. They are packed with tools and machines. I sure wish I was 25 instead of 65. I could do a lot more with them. I am just beginning my journey into the blue diode and CO2 lasers, and also a fiber laser. I bought a NICE 3D printer too. I am in the learning phase of designing, and that is why I upgraded from the free version of SketchUp. I have SolidWorks and Fusion 260, but I KNOW SketchUp, and now I can export .stl files from here!
