I have an inflatable mattress with a 17,3 mm air inlet designed for the included manual pump, but manually inflating the bed is a horrible chore... and I happen to own both a CompuCleaner and a 3D printer! So this new nozzle was the obvious thing to do: Bed inflates in a matter of seconds!
Print with a brim to improve adhesion and sand until it fits.
F3d file is included.
