We found the Socket Pal on here and wanted to make some improvements to capture the wrench and the extension better. So I created new files from scratch. I also made a more snug fit for the Craftsman sockets. Basically as is, this is specific to the Craftsman 12pc Standard/SAE socket set. We found that we had a scaling issue with our printer so I suggest that you make a test print and then measure the pocket for the extension. It should be 6.00 inches long. Then if you have to you can scale it to get a more exact print. The STL file will most likely come in mm and you will need to scale to inches. We started with 2540 scale in Cura and then adjusted from there.
