Trapezoid Ruler
thingiverse
This tiny geometric tool fits snugly into any pencil case or small pocket - a trapezoid ruler. Without any numbers, it lets you draw straight lines, as well as angles of 45 degrees, 60 degrees, 120 degrees and 135 degrees. Print it with transparent filament and the drawn lines remain visible on paper when holding the ruler up to it.
