The golden ratio calipers are cool, but what even the normal ones are really neat. I guess I never though about how simple calipers could be, because I always thought of them as rather complicated devices with rulers attached. I just made some simple calipers out of 2mm thick styrene and they work great. Cool video, and thanks for the idea.
That is AWESOME!!! The method I did can be applied to any material. I actually was going to make the set for the video from one of those thin metal rulers you can find at the Dollar Tree...but our DT did not have any that morning so I just used the sticks again. Thanks for watching!
