This is only for fun and looks a lot like the real wrench, you can use it for employee of the month/year or just for fun. See examples for best result of printing. When the roll-pin is printed the supports are easy to peel with precision scraper. To fasten the roll-pin you can use something like “LEGO Black Technic, Axle 4 3705 - 370526” or you make your own axle of 5mm. For a good result of the jaw movement you need to sand the imperfection of the jaw (thread) and the inside of the grip and use vaseline (mineral jelly).

Good luck
