This is an expanded version of The Socket Pal by TheTinkerGuy. The original version sizing was a little off for the socket set I owned, plus I had both a 3/8 inch drive and 1/4 drive metric socket set that I wanted to put together. This version holds 20 sockets in total (1 set of 10 sockets in 3/8" drive and a second set of 10 in 1/4" drive).

I included the Fusion 360 file I used in designing the file. It does include user parameters to adjust each socket size to fit the outside diameter of your set. Socket #1 was the biggest and go down in size order from there. I also included parameters for setting the spacing of the two rows and to compensate for printing differences. While you can tweak these figures for your own, the model is not perfect linked so elements of it could break and require tweaking to work depending on what changes.
