This is the second item I designed to print with my first printer and to continue learning the design software Fusion 360. The bungee clip or hook over the front hatch was misssing from the Native Titan 12 kayak that I purchased last year, and I hadn't run across any of the sliding style clips for that location. I had been using a mini double carabiner, but the new printer was a good excuse to make something... Its sized for 1/4" bungee cord.
