NOTE: rotate the X axis 180 degrees to flip it over for easy print.
a coworker wanted a tool to use for his upcoming fence project, he needed to be able to quickly locate the center of the top of a 4x4 post and mark it for drilling. a quick bit of google taught me that most posts are 3.5x3.5 but not always, so i made the center of this piece at 3.5x3.5 inches and the outer inside perimeter at 4x4 inches with a 1/2 inch hole int he center.
hope it helps someone else.
