I couldn't find a socket holder I particularly liked that also had magnet holes in the gridfinity base, so here's mine.
Holds shallow and deep 4-14mm sockets. I used Husky brand sockets (Home Depot) for measurements but there is a bit of extra clearance so other brands may fit.
For text filament swaps at layers 102 and 107 if you don't have a multi-color capable printer.
This design also include a slot for the 3in extension from husky.
