Water Bottle Cap

thingiverse

*** UPDATE 4/2/18 *** I've added some files for Fusion 360, along with a few other formats, in case someone needs to modify this file on the fly. A frustrating situation arose at work where my cap wouldn't fit onto the water bottles. They were too small and ridiculously tight. I'm not sure if it's because the water bottles are slightly different in size or if the filament used had unique properties that allowed for more shrinkage than usual. No matter the reason, you can now adjust the cap to suit your needs by tweaking its internal/external dimensions, wall thickness, and overall length to fit perfectly. This cap is designed specifically for 5-gallon water bottles. By re-filling these on my own, I've managed to save a ton of money (under $1 per bottle for filtered water). To keep them clean until I'm ready to use one, I needed a way to store them without dirt or dust getting in.
