Beer Shank Retaining Nut Socket

My homebrew Keezer/Kegerator collar has countersunk 50mm recesses where the beer faucet shanks come through. Tightening the shank retaining nut is tricky if you don't have a 28mm tube socket. Printers, assemble!

Accepts a 1/2" drive socket wrench, though hand tightening has been sufficient for my needs.
