3" PVC bulkhead

thingiverse

This is a simple bulkhead to allow attachment of store bought 3" PVC 90-degree elbows. The bulkhead requires a 3.25" hole for the bulkhead to pass through, but I used a cheap 3.5" holesaw from Harbor Freight and it worked fine. this was designed around the monoprice MPSM so the print surface was pretty much limited to what I can fit on the 120mm x 120mm surface. design has the thread tolerance built in, on normal print settings. threaded all the way without binding.
