Nsp surf fins (side fins for 3 fin system)(old nsp system)

This are the side fins for a nsp surfboard with the 3 fin old nsp system. I created them beacause nsp now uses a diferent system for the fins and I couldnt find them anywhere.
they need to be drilled after printing to place a nut to hold them to the board with a bolt.
Good luck and happy printing!
