I needed a compact storage option for sockets. This model fits 10 sockets with 9.5mm square holes.
I've printed it in PLA with a 0.6mm nozzle, with 3 perimeters, but I'm sure other materials, nozzle sizes and perimeter thickness will work similarly well, since it doesn't protrude very far off the wall.
It's similar to https://www.printables.com/model/679651-hsw-socket-holder-honeycomb-storage-wall, but more compact.
The author remixed this model.
Added a socket holder, to be insertet into the hollow inserts of the honeycomb storage wall
