Bad Faucet Extender

I'm so sorry you had to see this. I'm brand new to Fusion360, and I really didn't know how to do what I wanted. It kept giving me yucky errors about coincident faces or something, so I literally made an extra component and dragged it like 0.05mm or something to forcibly create an overlap so that I could combine bodies. I also screwed up somewhere along the line with my sketch faces, so now there's that little lip in the spout assembly. I don't know how to remove it. Someone please pray for me to the gods of Autodesk and Fusion
