The file 'Rigid Vacuum Port Model 3D Printer Model' is (f3d,stl) file type, size is 158.7KB.
I modeled the port to a Rigid Shop Vac. I have personally used this to attach to a five gallon bucket, so I can use it to collect saw dust without clogging the filter too bad.
I included the Fusion 360 file so you can do what you want with it. I'm sure there are some other uses for it.
