CAD powerbox fin template?

[mchaco1]

I just got a new fanatic SUP and it was missing the powerbox plug for the center fin. I imagine getting a replacement will be like trying to milk a rock, so I was wondering if anyone has a .stl CAD file of a powerbox fin that I could chop the top off of and send to the 3d printer... or just the top part if youdont want me to see your secret fin

As a guy who has converted many a fin in his woodworking shop, I can tell you this: It's 7 degrees off of vertical on the table saw.

Drawing gives the power box dimensions. The taper is 6 degrees not 7.

Well, that explains why I have to do so much sanding once it's cut! Nice to know the actual number, thanks.

P.S. Cutting down a fin head on a table saw is extremely dangerous & difficult, don't try it unless you have a lot of experience and a poor sense of self-preservation!
