This is a connector for my rainwater barrel outlet, so that I can connect a hose via a standard gardena adapter to it. (Files: Auslass-schnapp.stl) A 2.62 mm O-ring is required to complete.
Alternatively there is a 3/4'' to 1 '' Adapter, which also can be used. (Files: Auslass.stl)
Here are the main parameters: Tests and any comments welcomed. I do not know the name nor standard used at the barrel. It is this one: https://www.bauhaus.info/regenspeicher/4rain-regenspeicher-vino/p/25044995 I want to use the outlet on the bottom.
Comment for version 3: al though the threads now fit and work, I am not currently satisfied with the fit to the barrel itself. It looks like dome more distance to the hex-nut disk is needed. So I need to work on the version 4.
