Water Inlet Knob Wrench

thingiverse

The water inlet knob on our RV has one major design flaw - it's extremely difficult to grab onto when trying to turn the fitting. No more fiddling with this part, as we've found a solution. To ensure a smooth and effortless turn, I highly recommend printing out a 1mm prototype and giving it a test fit first. If necessary, you can then scale up or down until you achieve a snug fit that works perfectly for your specific print setup, just like it does for mine.
