NOTE: This part is superseded by an updated adapter that prints as a single piece. I do not recommend you use this one for future needs. It works fine, but it's a pain to epoxy together.
Two part adapter to convert DWV PVC Pipe to 4" Flexible Dust Collection Hose. Comparable to WoodRiver's part #151295. Parts must be glued or epoxied together.

Print with 0.3mm layer height, no supports needed. Approximately 3.5 hours to print both parts at the same time.
