Our RV uses a garden hose for the gray water hookup. I designed this to mimic commercial 4-in-1 sewer hookups: 4-inch NPT, 3.5-inch NPT, 3-inch NPT and 3-inch slip fitting. I added some tabs to help screw/unscrew it for the NPT fittings.
Updated 3rd version: Uses a 90-degree garden hose elbow (Amazon or Home Depot), which is less prone to clog than a swivel connector. You will also need a double female adapter (Home Depot) to connect the elbow to the garden hose. Print it with the flat side down, with support enforcers on the build plate underneath the hose connection; no supports are needed below the rest of the funnel. I used PETG, but ASA would also be fine.
Built in Onshape, here is a link to the model.
