My Echo PB 251 leaf blower was lacking the front nozzle so I made this one. The inside diameter of the tube is 75mm so if yours is similar it shoul work.

I made one with some decorative protuberations to reasemble the original but I also uploaded one completely flat that prints faster and easier.

It is 270mm long because that is the maximum Z heigth of my printer and I do not want to make it in to pieces but the original was a bit longer. Printed in PETG
