well, based off of the geocities image on google, here is what I have:
https://www.dropbox.com/s/ptzi3xhnkmn3rq8/powerbox.STL
There were a few missing dimensions so I did the best I could..Youll have to drill out the center hole for the brass nut and screw unless you can give me dimensions for those.
Also, on the drawing it shows that there is a cut corner on the bottom of the base. I am not sure if that is true or not so if you want me to modify it at all, let me know.
What are you printing this on? If you have trouble with it warping and such, let me know and I can do it on one of my machines at the office.
Good luck!

Good day guys, I'm an Italian guy and apologize now for the bad Language, I'm using google translator to help me.
IT WORKS,GREAT JOB !!
I realized the piece with my 3d printer and today I have tested on numerous boards at Lake Garda
the piece and 'just a little' tight, about 1.2 millimeters.
please edoremus337 you can adapt?
you can enter the holes as shown in the link below?

the screw hole is 7 mm, the hole of the nut is centered and is 9 mm
I tried for a long time to build a 3D design my fins but I never found anything until I read this thread on your forum, thanks

Hello, I have not yet tried the new stl.
I meant that the fin is a little too tight and moves into place on the board.
the whole thickness is expected to increase by about 1.2 mm
your video is very interesting, My printer is smaller and I will have to print the fin perpendicular to your print, I have to figure out if my final product is strong enough
I feel the stl soon
thanks

Wow, you have attached a bucket to your board. That is an object incapable of creating normal lift. Maybe has 40% efficiency compared to an actual fin purely though Newtonian forces and the drag will be immense.
