5 Gallon Water Jug Cap

thingiverse

I've found all the water jug lids I could get my hands on, and unfortunately, they're just too tiny. However, I've discovered that these lids perfectly fit Canadian-style water jugs - at least, that's what my research has led me to believe so far. Although it's not a watertight seal, I'm still figuring out the threading issue, this lid will do the trick for now and get the job done.
