Print the threaded adapter. Take it down to your home improvement store and find a copper plumbing part to screw in. Then search around for various elbows, reducers, and so on which will allow you to go from that 1" pipe thread to the inlet of your cooker. Solder or screw everything together and you're good to go.Looking at adding a damper to my UDS, but the two inlets I have are 1.5in.
Has anyone drawn an adapter that goes up to that size? The inlet valve is 1.5in so i'm guessing the diameter needs to be slightly smaller with an O-Ring to stop it falling out (It's not threaded).
I'm a complete novice when it comes to 3D printing otherwise i'd have a go myself :-S
