water barrel tap

This is a (cylindical) tap for the rainwater-barrel. It has a 3/4 '' thread.


This is work in progress! Please give me feedback if you tried to make one.

The barrel I use is this one: https://www.bauhaus.info/regenspeicher/4rain-regenspeicher-vino/p/25044995

I have made three different lengths of the Tap shaft.

I have made an experimental version which can be equipped with o-rings to make it leak-tight.
(If you can print with flexible filament, you can also print the o-rings (Oringe.stl)).
(I tested it. Id didnt work out well.) Do you have any idea how to get this thing leak-tight?

There is also a version without seal at the barrel connection.
