Water Bottle Cap

thingiverse

*** UPDATE 4/2/18 *** I added some files for Fusion 360 along with a couple of other formats in the event that someone needs to make a change to this file. I ran into a situation where my cap would not fit onto the water bottles at work. They were too small and way too tight. I don't know if this because the water bottles are ever so slightly different in size or if the filament I used had different properties and allowed more shrinkage that the last filament used. Regardless, you can now alter your cap to fit your needs by changing the internal/external size, wall thickness and its overall length to fit your needs. This is a cap to fit onto 5 gallon water bottles. I save a ton of money by re-filling these on my own (under a $1 per bottle for filtered water) and needed a way to store them without dirt/dust getting into them until I am ready to use one.
