Wingfoil / Hydrofoil to Paddleboard Fin Adapter

This is the first proper model I’m releasing, mainly because I couldn’t find anything like it on the internet!

I bought a wingfoil board with a US-standard box for mounting a foil. But I also want to use my board for paddleboarding and training without the foil. I tried to find printable models for this, but had no luck. So I had to create a fully functional Wingfoil/Hydrofoil/SUP adapter for standard SUP fins—with fast installation and safe transport.

This model includes everything you need to print:

1. US Foil Adapter / SUP Adapter
2. Bolt system with two options – 45-degree screw or printed nut support
3. Bolt cover

I hope this helps someone, because it took me several hours of testing and searching for the best and strongest solution. Thank you for any photos of you using it and for your feedback.

Have fun in and on the water!
