Recently I converted my old Ford pickup to diesel, and I needed to make a bracket to hold a throttle position sensor, which helps to control the new transmission. Often I wing this sort of thing, working from notebook drawings or cardboard models. But this time I decided to use 3-D CAD modeling, CNC manufacturing and 3-D printing to design and fabricate the part to the exact specifications I wanted.
When I’m building something weird—my pedal-powered Panzer, for instance—I have to pull together all sorts of obscure parts. Over the years I’ve noticed that I continually reuse some of them in project after project. here are the five that I can’t live (or work) without.
