The file 'Angle Measuring Tool With Increments 3D Printer Model' is (stl) file type, size is 1.1MB.
One set of arms has the inches incremented in fraction and the other has them in decimal. Also the other side is incremented in millimeters so you can measure in any scale you would like. I havent printed it myself yet but the increments are only .5mm gaps to bridge so should turn out just fine printed with ruler facing down.
