ELBI Water Valve Tool

Many comercial wash machines use the plastic ELBI water valve. To open the valve to install a new diaphragm kit, involves removing the stem. There is a plastic tool available for this, but it requires a wrench or socket and I am constantly misplacing them or nearly tossing them away mixed with old stems. I designed this one to have a screw driver style grip but also included a 3/8" square for a socket wrench if needed. I printed mine in orange so I can spot them in the bottom of my tool bag better.

UPDATED VERSION: Came across a valve that had a different style stem where my support ring intefered with engagement. So I removed the ring on the V2 STL.
