A small (100x32mm / 3.94x1,26in) PCB ruler made in KiCAD. It has a millimeter, a 1/8 and a 1/10 inch ruler, furthermore a protractor (for roughly angle measuring). Also this ruler helps you, when you want to create a PCB, because you can see different trace width and drill hole sizes in real life.
Quite small form factor (100x32mm or 3.94x1.26in), so its portable and it can be manufactured very cheap (you can panalize the design, so you can make two rulers per PCB) Metric Scale (mm) and two Imperial Scales with different subdivisions: 1/8 inches on one side, 1/10 inches on the other. Degree…
