Printed in PLA, it's prolly more of a tool than the original, storied, circular, open end wrench. The mechanic who told me the story had the actual item framed on his wall as a lesson on the cost of cheap tools. 

Printed in TPU it should be good for quietly slipping into the toolbox of acquaintances for their later surprise and delight.

Includes gcode file with color switch at 3mm to make the text pop.
