This vacuum hose hanger would be used to suspend the hose of a shop vacuum to the ceiling. I use it so that I can go anywhere in the room without having the hose always in the way.
This was printed with generic ABS. No particular reason. I just had a lot of ABS lying around. It would work just as well with PETG.
My hose diameter is 40 mm and this hanger has a diameter of 42 mm. It could easily be scaled up for larger-diameter hoses.
