This is a narrower tip for the Ryobi P2180 leaf blower. The intent is to get a narrower, higher velocity air stream to make the blower more effective for leaves on grass or uneven surfaces. The clips and tip cone attach with four #6 1-inch screws. I ran the clip file through Netfabb to repair it. The tip file failed in Netfabb -- it says failed to load mesh. I'm not sure what that mea but if anyone has trouble printing the tip or knows how to fix it, let me know.
