Brita jug water filter plug - Tapered Thread

I've been using the instructables (https://www.instructables.com/id/How-to-refill-a-disposable-Brita-brand-water-pit/) water filter re-use idea for a number of years but I never got around to having a proper plug for the filter. That was until I got a 3D printer !! :-)

Anyway, there are 3 Tapered Threaded Plugs for you to use. The smallest is possibly of no practical use in this application but I'm including it as it may be useful for other applications.

H=length of screw excluding head
