Air mattress pump adapter

thingiverse

Filling an air mattress is a breeze when you have this nifty dual-use adapter on hand. To get started, simply insert the pump outlet into the center of the adapter's large end - this will take care of filling your mattress to perfection. But what about emptying it? That's where the inlet side comes in, and that too can be inserted into the same large end for effortless deflation. This clever adapter is a game-changer, replacing three separate adapters that would otherwise be required for both filling and emptying the mattress. If you're planning to print this design using a 3D printer, you may want to consider scaling it up by about 3% to ensure that the adapter fits perfectly and doesn't cause any unnecessary clogging. And as an added bonus, polycarbonate is a great material for this project - just test printed one on your Makerbot 2+ and see the results for yourself!
