The attachment that came with my air mattress inflator pump required that it be held firmly and squarely to the mattress during use. This attachment screws onto the mattress valve and fits snuggly to the pump so you can set it down when filling.
Also, for quick and complete emptying of the mattress, you can attach it to the pump intake while the other end fits over the mattress vent without leakage.
Fits pumps with 25mm (1") output and intake. When unscrewing after filling, be sure to hold the valve so you don't unscrew it from the mattress and let all the air out.
Use flexible (30D or 40D) filament.
I've also added a press fit attachment for filling mattresses that don't have a screw connection. Print in in PETG or PLA.
