90º drain elbow larger than 110mm dia. (Euxton PR7)

I need a 90º drain elbow at around 125mm dia, similar to the one in the photo, but doesn't need flanges at both ends, one end will do. This is for a Hedgehog feeding station, The one in the photo is only 110mm dia, and is now too small, we have a Hedgehog visiting, but is a bit larger than the pipe.
