Here is an adapter that screws onto standard 56/64-27 thread faucets (after removing the aerator) and allows a standard 1-1/6-11.5 garden hose to be attached to the other end. An additional o-ring or two may be required to prevent leaks. I would also recommend printing at a layer height of 100 microns or lower (50 micron recommended) as the threads are pretty dense. Also, print without supports.
