All I can say is WOOHOO!!!! The fins work perfectly, just like a new set – I have to admit even I’m surprised! Since they work so well I’m giving them away for FREE so anyone can print a set and let me know how they go. Just follow this link to my Thingiverse page.
I might print a few more so I have spares in my kit, but the next step is to try printing some different shapes and sizes so I can really compare what works, which conditions, how fast, how high etc. 1 or 2 top secret ideas as well 😉
Great little 1 week project, if you do print these fins out please let me know how they go.

Hi James.
Thanks for all your free designs. I’ve just printed a kite fin.. looking forward to trying it out!
Could you tell me how you modelled the kite fin? I would like to create my own 3D model of one and also a surfboard fin – but not sure where to start. I’ve been learning both DesignSpark CAD and Blender. Really after the technique or steps you took – probably not specific to an app.
Thanks again

Thanks for getting in touch Tim. I haven’t used either of the CAD programs you’ve mentioned, this fin was modelled in Solidworks, But the process is probably pretty similar no matter which software.
The way I did it is basically if you imagine the shape of the fin sliced into 3-4 cross-sections along its length, I’ve drawn these as 2D sketches, and then lofted them together to form a solid shape. Hopefully this link will help give you a clearer idea what I mean https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-0A041818-2E32-4212-A3D8-CE0361C3D229-htm.html

Hi James.
Thanks very much for this – it’s something I’ve been wondering how to do for quite a while. Kind of obvious now you mention it. That image of the fin in link you posted is a great example.
Much appreciated
Tim
