Connects a 1-1/2" corrugated hose (common for sump pumps in North America) to a 3" threaded PVC cleanout fitting. (I needed to make that connection reliably, with very little vertical space. See the third photo - this was the situation I inherited. No further comment.) This coupling is not watertight; it fits the case where your sump pump hose is draining into a wider pipe that will drain downward. I printed this in PLA once (pictured), and it cracked after some months; not sure whether a work crew banged it up accidentally or it died due to stress. So, I printed the replacement in glass-filled PLA, which seems like it's doing fine. A couple of contractors have needed to replace or modify the hose since I installed this, and they both figured out how it worked without asking me, which I took as a design victory.
