About this model

Great design but I wanted a few more bolt sizes. I recreated this from scratch in Fusion360 and added M6, M8 and M10 bolt sizes. It can now measure up to 100mm bolts. The one I printed was printed in one color and I just used a sharpie to darken the letters and numbers. I plan to print another and do 2 colors.
