Fan blade duster adapter

I have a fan located very high up (18feet) in my living room.  Bought a extension pole meant for swimming pools that is 3 sections.  Printed this adapter that fits in the center and added a clip to secure it.  It has a hole on top that you glue a modified Swiffer dry duster handle.  Modification to handle is to remove the handle part and using a heat source (hair dryer) bend the part so it is 90 degrees.  I glued the modified handle to the adapter with Loctite Shute glue which I think is similar to E6000 glue.
