The purpose of this adapter is for use with common sealed barrels/drums. It can be screwed on from the outside by holding the inner piece in place through the hole without the need of creating a larger opening at the top.
I'm using it together with a 208l plastic drum which only has small screw cap openings. This adapter will fit through a opening <50mm.
To use the adapter drill a 30mm hole in the barrel. Insert the inner part from the inside with the help of a string or something similar. I used a garden hose which was rigid enough to easily guide to the drilled hole. From the outside it is then possible to hold the inner part in place while screwing on a cap which fixes everything in place.
The outer cap has a 26mm thread to fit together with common water barrel taps found at the hardware store.
A gasket with a ID of 30 mm is needed to seal the barrel and the adapter. Also use the gasket the comes with the store bought tap.
Update 2026-09:
Added a "straw" that can be glued on the back of "part1", if positioned downwards it will suck water from below the tap and also reduce vortex-forming when the water level is low.
Printing recommendation:
Use a extrusion multiplier slightly larger than 1 to achieve a water tight print. I used 1.05
No supports needed.
