Summary

I added threads to this for a standard telescoping painter's pole. Surprisingly those are not "standard" threads, so many thanks to those various people on Reddit that suggested the basis and how to scale those threads to incorporate into this model.

Printing this, you should be able to just screw the attachment onto a painter's pole you'd get from home depot and easily sweep your gutters.

I recommend 15-20% infill for the main body of the part, but using your slicer's tool to do a different/custom infill for the threaded portion at 100%.
