Swimming pool water pump air-release valves' wrench for Krystal Clear Deluxe Saltwater System Model 8221

This is a wrench for the Intex swimming pool "Krystal Clear Deluxe Saltwater System" Model 8221 water pump's air-release valves'. These valves are for releasing the air if it gets into the water path and make the pump work efficiently.

Sometimes these valves become difficult to unscrew especially when hands are moist.

Also made a kind of "light" version which is 5mm thick in case someone needs it printed quickly and thickness doesn't matter too much.

If you found my design useful or inspiring and would like to buy me a cup of espresso you are welcome to tip me:
