Ruler Compasses

thingiverse

This unique 10 cm ruler features holes for enhanced precision when marking with a pencil, preventing blurred lines. The larger hole allows you to attach the sharp cone tip, transforming it into a compass. To draw straight lines, utilize the inclined part and measure distances in centimeters using the relief lines. For precise point markings, insert a sharpened pencil into the dots. By placing the sharp cone in the largest hole alongside a pencil into one of the remaining holes, you can employ this ruler as compasses to draw circles with a diameter ranging from 2 to 20 centimeters.
