Barrel Bung Wrench

thingiverse

This is a hand wrench for the recessed cap on the common 15 or 30 gallon barrels used in many industries. I use them to haul water to a remote property and the long handled wrench people normally use is too long and cumbersome to use on a regular basis. This is much easier and fits in the door pocket of my truck, so it stays where I need it.
