My mom bough a huge pool slide for my nieces and nephews, and blowing it up with a hand pump or with lungs was definitely a no go, but the compressor I have needed the tip of the Blowgun to be a bit bigger so it would seal with the mouthpiece, I made it out of Duct Tape, but designed this rigid threaded tip in case anyone out there needs a replacement of the original rubber tip, or doesn't want to or can't print my TPU Cover. This is a complete solution that should fit most inflatable toys.
