In a moment of panic, I was scrambling to inflate my kids pool during a heatwave, but I didn't have anything to inflate the pool. I had my air compressor which could obviously get the job done, but my blow gun attachment was way too small to interface with the larger Boston Valve of the pool. So, I printed this adapter that interface between the pool and blow gun. Be a summertime hero with this super simple adapter and be the envy on your block!
