3D model description

Two designs of FCS softboard finboxes:
One to be installed into the board and one to be attached onto the board - i.e. which does not require cutting into the board.

For both versions you will need M4 screws and nuts to attach them to the board.
The length of the screws depends on the thickness of your board.
Furthermore, you will need 3mm grub screws to secure the fins, or you can also make the holes bigger and use normal fin screws, but those are a lot more expensive.

The distance between the screws for attaching the fin-boxes to the board is 10cm, which is the distance for e.g. olaian softboards.

Print at 100% infill!
Supports are not required!

I haven't tested the fin-boxes to be installed into the board yet.

However, I have already tested the adapter-version and I'm very satisfied with the result.
I use it on my olaian board in combination with the mini fins you can find here:
In my opinion it works a lot better for river surfing than the original fins.
