Radius Caliper Adapter No Computation Needed

Inspired by the model of the same concept as shown here on printables: https://www.printables.com/model/236582-radius-caliper-no-computation-required I wanted to rectify one major downside to the original design, being that the acute angle doesn't allow you to measure radiused corners greater than 60 degrees. This adapter uses the same math to provide a direct radius measurement but has one major advantage. You can screw in M3 socket head screws to act as a stud. This enable you to measure radiused corners that before were not possible. At the same time, there's no conversion or math to determine the radius. The screen shows the exact radius (plus or minus margin of error of course). I've also included a small window so that you can ensure your caliper is seated all the way. The caliper I used is a model from Husky, they are inexpensive at $25ish dollars. It's very likely that your calipers will fit as well. I've left no tolerances because side to side runout will affect accuracy. So y
