Hex Wrench

At 100% size, this is a 10 mm hex wrench. To get other sizes, just increase or decrease the size of the wrench in your slicing sofware. For example: if you need a 6 mm hex wrench, print at 60% size. If you're printing in PLA, make the 3D model a tiny bit bigger because PLA tends to shrink when cooled. So if you are printing the 10 mm hex wrench in PLA, print it at 100,3% size or bigger, depending on your printer's settings.

If you print this wrench, feel free to send me a picture of your res
