This is a quick print to adapt the output of a generic air mattress inflator blower to the hoses used with a Platypus gravity water filter system. The OpenSCAD file is designed to let you adjust the inner and outer diameters of both ends, along with the length of the wide, middle, and narrow parts of the adapter, so it should be possible to adapt it to your specific equipment.

Print instructions

Not a demanding print. Shouldn't need support. Worked great with generic PLA.
