Twintip symetric fins, 38.1mm or (1.5 inch for imperial USA) hol


Built my first ever kiteboard and the other fins on here weren't quite to my taste. This one is mathematically designed and with a round leading edge. Google the "Coander effect" if you want to see why I didn't make the leading edge sharp. :-) Dimensions:137.2 long x 8.98 thick x 40mm deep. I'm only just learning kiteboarding, lots of on line research and I've windsurfed lots but I haven't rigged up and hit the water with a kite yet. See the instructions too, it's a big ask to 3D print plastic durable enough for stresses of real life use on a board like this! Second part is a mould. Mirror image to get second half of mould!
