This is a socket organizer I whipped up because I was disappointed in the ones available. If you print it and like it, please post a make! I designed this around pittsburgh pro 3/8" sockets, but they should work for others.
Set your support to 75 degrees, 10% dense, the only thing that needs support is the tabs for the flat socket pockets.
I drew this in Autodesk inventor. First, I measured all the sockets and put them into a spreadsheet that organized them by major and minor diameter, and then added 1mm of extra diameter to each. I drew up the basic shape, and then extruded or revolved each profile into the basic shape, ensuring 2 mm of space between every feature
