I bought a cheap plastic boat hook attachment and wanted to use it with a telescopic painters' pole for a longer reach. I adapted the thread from fuferman's Swiffer attachment, adding a couple of turns so it completely screws down on to my Harris paint pole.
This was a tight fit in my boat hook, so I tapped it in with a rubber mallet. You may want to scale it down slightly (99%?) in X and Y when you print it - there is enough slack in the internal thread to allow this.
Update: the .3mf file is using the PrusaSlicer merge and negative volume features to compose the model from several parts. I've added a pre-processed .stl file that you can use with other slicers as well.
The author remixed this model.
