I love the design, I'm also rmaking some fin. I would be interested about the kind(s) of plastic you used. Thank you

I made this and put it on my Airush compact and attempted to kite surf with this fin. It Slowed down the board, felt like surfing in molasses but it made lower speed turns easier than a generic fin. I used it for a couple of hours, but it broke off while using on a wave run. I think it should be made thinner, but great idea!

Early version of this fin broke off due to high side loads. I recommending printing at 100% infill. I also increased the base thickness so that side loads are transferred to the main body of the fin, rather than being all absorbed by the tabs.

Time to print at 100% infill (on Makerbot 2): 6 hours
