Older RYOBI 40V Nozzle Extension

Summary

This is a reducer extension nozzle for the Ryobi RY40470VNM(?) 40V cordless leaf blower modified in Tinkercad. It helps make the airflow more concentrated and extends the discharge quite a bit.
It's a friction fit inside the end of the tube  with an added flange to allow bolting to an existing flange on the original blower nozzle. If your original doesn't have that flange, the friction fit seemed enough to hold it in place. I printed in PLA+ and it seems to be holding up.

As the original designer did, I have included a test ring that is the bottom 5mm of the print so you can make sure it fits properly without printing the entire thing. I also included another test flange and ring so you can test the complete fit without printing the entire thing. The flange and ring piece is the bottom 35 mm of the nozzle extension.

You may need to scale the print up or down a couple percent depending on the tolerances of the inside of the discharge tube that is included with the blower. Note: the holes in the flange should be okay (They are 3/16" or 5 mm holes). If not, do a print without them and match drill through the original flange and the extension flange.

I've never done a share before so let me now if you want more info.
