Screw Diameter Testing Tool

This is a handy tool for 3D printing hobbyists quickly find the diameter of screws they are working on to help you create better, and more accurate models. I personally use this tool to help me design custom parts for machines in my home, but you can you it for so much more. You use it by putting your screw into each hole until you find a perfect fit. Once you find the perfect fit, you must find the number on the same row as your hole and count forward, knowing that the each hole has a 0.01 in diameter larger than the hole to the left of it. For example, the hole right next to the number 0.26 has a diameter of 0.26, the hole to the right of that hole, has a diameter of 0.261, and so on.
