I have storage trays for my regular sockets but all these various hex bits and socket adapters had no home in my tool drawer.  

This tray has hex indents for 1/4" and 5/16" hex bits and adapters, and square posts for 1/4", 3/8" and 1/2" socket adapters and unusual sockets.  The base measures 80x180mm, so it just fits on a Mini print bed without the skirt. I included the F360 design file if anyone wants to modify it. My gcode has varying infill with 15% adaptive cubic for the body and 25% gyroid for the square posts; I also increased the top layer count to 6.
