Air Pump Coupling

It was tiring to fill our inflatable boat with air from our manual pump. Our electric air pump had no means to attach to the boat, until now. I designed a coupling that allowed the joining of two 20mm pipes together. The two pipes, the pump output and the input to the boat fitting both shared the same male 20mm fitting. Unfortunately, I could not source a female to female coupling. The coupling includes a mounting hole on the side of the part to allow the coupling to be secured with a cable to dangle from the air pump when not in use. My print is made in 1.75mm eSUN PLA Plus filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer. Print supports are optional. I hope you can find this print useful, too.
