How to design and make humpback whale inspired surfboard fins

Just standard volan layup, cut the template (sans bumps etc), foil the rough template, cut in the details, then foil the tubercles. Takes a bit ::slight_smile:

Did anyone try printing in nylon, polycarb or carbon-fiber-infused nylon yet?

Thermoplastic polyurethane looks too flexible but would be great to try!!

 

Certainly have, but without success.

Must be buried somewhere in this thread or nearby:

Using the materials you mention would only possibly work with a very hot heated print chamber. 

I was thinking of getting a pro to print it in nylon-carbon fibre but I can’t find a copy with the base on it.

I finally lost my fin today. Gutted! It’d been a while since I’d tried it (gulwhale), and I’d forgotten how much better it was.

Here is a link to my nylon-carbon print attempt:

Below is where you can get the file for the fin and base:
