There are three ceiling fans with chains I can’t reach in my house so I created this tool.  The design consists of a chain pull head and a handle butt end.  They both fit inside ½” D2241 PVC pipe (ID approximately 0.71”, wall thickness approximately 0.065”) which you will need to cut to length.  Alternatively, you could print sections of tubing and glue them together.  I chose to glue the butt end in the PVC and to use 2 screws for the pull head.

Note that in a pinch, this makes a pretty good back scratch tool.
