Painter pole cap for wire antennas V2.0 with guy line tie points

Version 2.0 Update: totally redesigned threads created in AutoCAD and test fitted to several commercial painter poles. This version also includes guy-line tie down attachment points.

I've included an STL of just the threads if you need them for another project. The thread body is 30mm tall x 29mm dia.

While windsock fiberglass poles (up to 33' high) are good for very light wire vertical antennas, they are not great for EFHW, dipoles, inverted-V's, or anything with weight. For any of these other antenna options, I wanted a pole that was rigid and could take the weight - and the most common and easy to find are long-extension aluminum, fiberglass, or carbon fiber painter's poles (available up to 30' long).

For use in an umbrella or flag stand to put up wire antennas (EFHW, dipole, windom, etc.) Aluminum painters poles are rigid and a good match for heavier antennas, so I needed a good tie-off point on top for them. I have hitch-mount flag pole holders for my truck (front and rear - yes, I also have a front hitch). Aluminum poles might interact with a wire antenna system, so pick the mast material carefully (consider FG or CF).

Printed in PETG Carbon Fiber, 50% infill, 6 shells, 6 loops, 0.16 layer height, threads require supports (I used tree/slim/auto). Takes about 63g of filament. It is very rigid. If using supports, set your top/bottom spacing between 0.30 and 0.35 to make them easier to remove.

This was designed in Vanilla AutoCAD 2027.

My wife calls it the Minion Pole Topper.
