This is a minimalist list defined socket tray.

My sockets are all Craftsman sockets from about 20 years ago. Craftsman has used multiple suppliers over the years to make sockets for them, It is unlikely that your set will match mine, so measure your sockets and adjust the dimensions in the list so they match your sockets before wasting plastic printing the wrong size tray. I included the lists I used to print out my tray's, and left them commented out in the source file. Use these as examples, but don't trust the measurements to match your sockets. I did have to break the 1/2" drive metric socket tray in two because it would have been too long to fit on my printer bed, even diagonally.

I did not bother making multiple rows align other than inserting fake dimensions for sockets I don't own. If I ever get those sockets, I will probably have to reprint the tray.

Edit: I bought the sockets I was missing, and found that they did not quite fit the holes whose sizes I guessed at. Also, it irritated me that the sockets of the same size did not quite line up, so I updated the socket tables to add in the parts I originally did not have, and correct some minor size issues. I also added two new options "Align", and "Justify" Setting the variable "Alignment" to "Justify" will widen the blocks of the shorter rows so that all rows are the same length (this is like right justifying text). Setting the "Alignment" variable to "Align" will set the width of an object to the maximum with of all objects in a column, so the parts will line up vertically, even if they are not all the same size.
