Summary

This is not a rermix of the Gutter Gripper, but an addon. The screw tab on my Rain Sensor broke, so I designed a recepticle that can hold the Rain Sensor and can get attached to the Gutter Grip that davelh designed.
Go to https://www.thingiverse.com/thing:6617423 for the original gutter grip part.
The little hole on the side is there if you need to secure the Rain Sensor in using a self tapping screw.
