I created this square that allow marking on both perpendicular sides. It allows also marking the distance from the outer edge at 5 to 40mm and the angles (not marked): 15, 22.5, 30 and 45 degrees. There is another marking for 33.5mm used for concealed hinges (6mm from edge). I did not manage to create an origin for the angles but I wanted to make a smaller square.
UPDATE 10.08.2020 : Added the second version which is thinner (2mm) and the lower lip is 9mm for marking the middle of 18mm laminate boards.
