as it turns out I have a 3D printer and laser cutter so I COULD build "3-D printed and real precision parts." Just need .stl and ,svg files of those parts. just need a scale drawing and I can make those files in Rhino6 and CorelDraw. Also, I am building circuits in Eagle and I know a cute Chinese girl at a circuit building place in China so I can get them built in a few weeks. So I have the bases covered,
I'd be happy to make them for you for the same price as your book!
