This is a two piece "clam shell" fitting that encloses the stock humidifier hose that comes with the AC Infinity humidifier. The fitting is then clamped around the hose and held in place a nut. Works great!. I've added two nuts, one with a -.3 offset(loose fit), and the -.2 offset(tighter fit) as well. Printed with 20% infill and with supports on the baseplate only. Print an extra washer to "sandwich" the tent fabric between the two washers. I used the -.3 offset when printed with CF filament. I assume this would work on similar mfg with the same type tubing.
