This is a remix of AaronOaks ¼" socket organizer. There were a few sockets that I didn't come with my Kobalt tool set so I removed them. Numbers were rotated for ease of reading. Measure your sockets for fitment before printing. Sizes of sockets and holes are listed below.
Socket/Hole
5/32 thru 5/16 / 12.8mm
11/32 / 13.8mm
3/8 / 14.8mm
7/16 / 16.8mm
½ / 18.8mm
9/16 / 20.8mm
