As it is Boardmasters this coming weekend we thought we’d do a practical(ish) test to celebrate surfing. As usual the material is 100% recycled nylon from fishing nets previously used by the Cornish fleet working out of Newlyn Harbour.
The fin is printed at 50% scale, but otherwise an unedited version of model 604461 from Thingiverse
And before anyone asks, you’d have to do some extra engineering before it could be a useable demonstration rather than a test piece.
Personally I’d separate the fin body from the FCS mount, I’d remove the infill and leave a sleeve cavity for a second piece which included that mount, I’d glue the two pieces together then wrap the blade in some Carbon Fibre & epoxy to make the whole thing waterproof.
