I designed this Contour gauge to measure the odd surfaces that cannot be measured with common measurement tools. As far as my requirement the measurement resolution is fine for me but if any of you need a higher resolution you can decrease the breadth of the scales. I have printed 65 pieces of the scales(2 extra). Watch the video to see how to use the gauge, also support me by liking and subscribing the channel. Thank you. https://youtu.be/nFnnhOyiyYI
