This is a socket organizer for 3/8 metric sockets. Specifically I modeled this after the Gearwrench socket set. It may work for other brands, but it seems each manufacturer has slightly different dimensions. You may want to do a test print of the very top few layers and see if it will fit your sockets.

Additionally I will upload the Fusion 360 (f3d) I made for this. It is a fully parametric design so you can just adjust the parameters and edit the text objects. The spacing will auto adjust.
