I tried a couple of other ones, and they didn't fit the 6mm Snap-On socket I've dedicated to this project. This is a friction fit. Once the socket is pressed in, pliers will be needed to remove it if desired. No worries of it falling out! I also prefer the basic hex shape for the handle, rather than a less ergonomic spiky shape. YMMV.
The power supply case for my Creality CR-10S is steel. I made a recessed portion on the bottom of the wrench for a 15mm x 3mm disc magnet. I applied a drop of super glue to secure it in place. Now I can put the wrench on the case, and it stays in place. One less misplaced tool.
I've included the Fusion 360 file if you'd like to tweak it for your needs.
