I wanted to mount a Ubiquiti AI-Pro security camera above my fence using one of the posts. I printed mine in Prusament Galaxy Black PETG. Sized to make it easy to use the Ubiquiti tightening tool. Careful pushing backwards on it when it's screwed in place!
Improvements I'm thinking about: more body to push the camera farther forward, thicker back piece (there is one skinny section that could be more robust).
The author marked this model as their own original creation.
