Just a small fishing rod holder. Requires two units and they need 2 screws each. The print quality does not really matter since its not going to hold that much weight. My rod is approximately 23mm in diameter in the thickest spot. According to fusion 360 it should be able to hold a rod to a max of 28mm in diameter in the thickest spot.

The wall mount is meant for at 2 piece rod and can be placed what ever you like apart from each other.
