A replacement hose swivel end for the Craftsman 113.177805 8 gallon wet/dry shop vac. The hose swivel end is the part that connects the hose to a nozzle (see photos).
I used PLA with 15% infill and 0.3mm layer height (just because it is faster). Consider a brim (I had a failure without one) as there isn't much print bed contact area. No support needed.
From the manual: NOTE: The swivel end of the hose is removable if more hoses need to be attached for more ength from the vac. To remove the swivel portion of the hose, grasp the hose swivel and firmly pull it out of the flexible hose. Connect the soft end of a second hose (accessory #9-17820) into the swivel end of the original hose by forcing the sections together until they fit tightly.
Trivia: The taper is half angle is 1° and starts at diameter 57.7mm
