This is my design for the "Canoe Rodholder Challenge". STEP and IGES with detailed pictures and my explanation will be up tomorrow.

P.S. The fishing rod in the picture is not mine, I got it here: https://grabcad.com/library/fishing-spinning-rod/files
It was made by Andrey Jasiukaitis. I only used it to show the functionality of my holder.
