Fender / Dock Bumper Hanger for Pontoon Boat

thingiverse

Dock Bumper / Fender hanger for the square rail of a pontoon boat. Designed to hang a fender on a 3/8-inch line/rope with a simple knot tied above the hanger hole. It is easy to slide the hanger on and off the rail in seconds as you approach or leave the dock. No need to tie or untie the knot in the line. Just leave the hanger attached to the line for next time at the precise height you want for each bumper/fender. These are made to fit a 1-1/2" square rail, but have a slightly larger opening because my rail has a small bump out/bead that it needs to fit over. You should be able to scale as needed. Print on the side to minimize the need for supports except for the hole. May be able to do without hole supports but may turn out a bit rough.
