Intex air mattress connector / inflator adapter

thingiverse

Using a DeWalt inflator when camping, none of the tips in came with worked well for inflating my Intex air mattress, which has a self closing valve that can only be pushed in so far. I could not get a decent seal. I modeled this so the standard nozzle of my inflator pushes in and seals nicely on a taper which should allow some variation. This mates to the Intex air mattress valve with a push and twist, and a hard stop, pushing the button seal out of the way, and allowing air flow from the sides of the adapter while it stays in place. I designed with this with a groove to use a standard O-ring (size 216) to get a perfect air seal, but even without the O-ring, it makes life a lot easier for both inflating and deflating. I made this from PETG with 100% infill, but I overbuild everything. You could easily reduce infill and use PLA successfully.
