There are already many great gridfinity models for organizing imperial sockets, but none had exactly the sizes I needed for a random Kobalt set of 8 imperial sockets.

The sizes are: 

1/4"

9/32"

5/16"

11/32"

3/8"

7/16"

1/2"

9/16"

I printed on a Bambu A1, PLA basic red, PLA matte white, 0.4mm nozzle, default settings. I assume pretty much anything will work.
