Mercury / Mariner Inflatable Pump Nozzle

thingiverse

Tired of constantly purchasing new inflatable heads due to lost or overboard incidents? Replacing them every time can be frustrating. At least one ring must be printed in flexible material, preferably FLEX, for optimal durability. To ensure a snug fit with the valve, feel free to combine multiple rings as needed. If necessary, use a small 16mm-long screw that is 1.5-2mm wide to gently push on the valve and secure it in place.
