I have an Echo brad leaf vac and when I wore the bag out I bought a Works brand hose and adaptor kit so that I could blow the leaves directly into a 55 gallon trash can. The Works kit came with several adaptors to fit other blower and a universal connector shown to fit other brands. I measured up the ends and printed this adaptor so that my works hose will connect directly to the blower. I used pla filament because that is all I have right now so it will be interesting to see how it holds up with leaves and small chopped up twigs blowing through it.
