Description
In the US, a glass gallon jug (also half-gallon) frequently has a standard 1 ½ inch (approximate size) cap. This model is for such a cap. I made mine from PETG but I suspect it would be good in most materials.
It includes a gasket (liner) that you can make out of tpu or other material. Or just cut one from something, or leave it off entirely.
Fusion file included as well.
