This adapter screws into a cheap Harbor Freight blowgun (and probably others) and fits inside the Intex air ring hole so that you can use an air compressor to fill up the ring. If you have a different size plug to fill or a different size blowgun, you may be able to use the customizer function to modify the sizes (but I haven't tested this functionality). You might also have to tweak the parameters of the blowgun threading depending on your printer tolerances (I ended up enlarging the threads 0.5mm in diameter more than the measurement I got off of an existing blowgun tip for the .stl I included).

Make sure you set the PSI on your pressure regulator to a low number so that you don't accidentally over-inflate the ring and cause holes.
