A quick remix of kamilice22 go pro mount, and my own adapter(https://www.printables.com/model/36039-bunnings-paint-pole-to-gps-thread-for-surveyors )
Printed with PETG has been fine for me when connecting straight to the go pro ( no extenders etc). With this thread I normally have to tighten and loosen the thread in the first time to smooth it out.

The author remixed this model.
