I printed the various socket organizers, and my son has this set of Pittsburgh color-coded metric deep impact ½" drive sockets he asked me if I could print him a tray. I couldn't find one already made, and did find the actual sockets modeled here: https://grabcad.com/library/pn-61288-metric-10-piece-color-coded-deep-wall-socket-set-10-19-mm-1 which saved me a bunch of time measuring them.

It is too big to lay flat on the print surface, so I print with supports on edge with it rotated to fit on the build plate. I'll probably revise this to include some magnet pockets to help keep the sockets in the tray.

Version 1.1 the socket pockets in the tray are the exact measurements of the sockets and the sockets stay in the tray.

Version 1.2 the socket pockets in the tray are 1mm longer than the ones in v1.1. 

Version 1.3 the socket pockets are now oriented smallest to largest from left to right, with the drive side facing you.
