    I was thinking if we were to design a basic cheap functional vernier sextant today if we would do it differently with the availability of 3D printing. Still the same problem of course unless you include some kind of friction device. I was thinking about the way cheap vernier callipers have a thumb wheel to move the slide slowly.
