This fits a DW735 or a Dewalt 735 Planer. This is the same size on both ends but it's 1.5" shorter so the Street L Elbow is not so far out there.

Works great. I remixed some parts I found on Thingiverse and added the 4" for the street L Elbow. I plug my planer into a 4" hose that goes to a trash dumpster.
