The WeatherFlow Tempest weather station can mount to a 'standard 1" pole', which is really 1.25-1.31 inches in diameter. I have a long telescoping pole made of square tubes (1" inside 1-1/4" inside 1-1/2"), and this allows me to mount the Tempest securely on the end using a 3/8" bolt.

I used to printing this with the open end on the bed, it occured to me much later than starting with the flat/solid end results in a cleaner print. This sits at the top of a nine foot pole, which itself is four feet off the ground, and is exposed to the elements (think "windy"), I wanted it to be as strong as possible. It's probably a bit too strong (thick walls and significant infill), but it doesn't hurt anything :-)

Other things can mount to a 'standard 1" pole", most often lights (think stage lights).
