5 Gallon Water Jug Cap

thingiverse

Simple self-latching cap for 5-gallon jug refilling. Push it on to attach and pull to remove. *THIS WORKS ON MY BOTTLES - YOUR RESULTS MAY VARY* Created for 5-gallon bottles with a 56mm outside diameter mouth. You will need to print one Hub and four keepers. The keepers require a 1/8" bungee or shock cord. A rubber band may work too. You want the keepers tight when the cap is put onto the bottle, as they keep it "locked" in place. Lastly, you'll need some thin foam self-sticking mat. I got mine from a local craft store and cut it to 56mm diameter, then stuck it inside the Hub. ~~*This will not keep back 5 gallons of water. But it will prevent water from sloshing out during transport.*~~ **UPDATE: Welp, I was moving a full bottle on a hand truck through my yard when disaster struck! The bottle fell off the hand truck and hit the ground, landing on its side. Not a single drop was lost!** Your mileage may vary!
