Unfortunately, I could not source a female to female 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 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.
