Water Jug Vent Plug - Easy Insert

The original works great, but it was a little tricky to insert into my water jug. I ended up sanding the tip down on one of the fins and it went in a little more easily. I figured I would do a remix that did not require any sanding. It's still snug and does not come out by accident.

When inserting, try to apply the pressure as close to the fins and the jug as you can to avoid snapping the shaft.
