Version 3.0 of "hands free water cooler valve" allows you to open the existing cooler valve and keep it on by rotating the knob clockwise or by pressing in on the knob for conventional use. Simply slide it on the push button water spigot valve found on most water coolers (igloo, gaterade, powerade).
Designed for 11mm hex bolt in the knob and two 11mm nuts inside the mounting piece, this allows the knob to slide in and out without wobbling.
No supports needed if you print it upside down from how it is used in the video.
