Basically, the piece to my shark vacuum that the hose drapes over broke....so I drew a new one. And it worked! the tube it fits around is 31.8mm and that hanger was super tight, I had to pry it Open with a flathead a little then it went in fine. Not a terrible problem. I am sure this could be resized for any use. I will throw in the solidworks file as well. Dont be too mean on my modeling style, I rushed it :) *Also, i printed mine with brim using supports from meshmixer, and it worked pretty well, minor overhang issues that are mostly my printer. Feel free to try that one as well.
