I bought the Pittsburgh nut driver set with overmoulded handles from Harbor Freight and found that only the ones with the uncomfy resin handles had a gridfinity option. I initially printed this with walls, but they ended up breaking off when I handled the container, so I just removed them.

Fits both metric and SAE, recommended to only print out of PLA (Tried ABS and this print warped so hard it peeled the steel sheet off the magnetic bed on my voron). Gluing down some pretty paper is optional, but recommended.
