This is a 1/2" drive 7/8" Thin Wall  Spark Plug Socket.   I couldn't get one locally and ordering one would take too long so i made this.

I printed this in pla+,  standing up with supports on bed only and a brim.   If you need it for  higher torque use you may try printing it on its side, and with a different filament, but so far it's worked well for me.
