Summary

24MM socket for undoing recessed faucet hex nuts with a regular monkey wrench. This socket was made to fit the specific tap nut I was wrestling with, but who knows, maybe it's useful for someone else. I printed the part in PLA. Just make sure to set 100% infill and print at a nozzle temp high enough to fuse all layers together.

You may have to file the inner surfaces a bit before it will slip over the nut. A tighter fit means less chance of breakage, so this is worth the effort.
