400mm Calipers

160mm and 200mm was not enough. A ruler is not as precise. x1 + x2 = 400mm calipers. Ive seen 200mm go for over $100.. Remove the end stop tab on your digital calipers (scary!) and slide on a longer ruler. The groove should fit the depth gauge as well. One will be added to the design in the future.
