I finally got my rain sensor and decided i did not want it constantly dumping water on a fence post so i decided to use a bracket and i customized this https://www.thingiverse.com/thing:3404532 but i needed a platform to sit on top to mate the sensor and the bracket.

The bracket itself uses the 1 layer bridge for the holes. If you are running thicker layers than 0.2mm you might want to tinker it a little bit. https://www.tinkercad.com/things/aOTECbNegb0

i used petg for sun and rain resistance.

I did not support the bridge because i wanted to have it even without having a lot of cleanup since this device does need to be level to work.
