Used the original model as a baseline for the normal fins - thanks for the design!
(original model: https://www.thingiverse.com/thing:1324570)

Reduced the size to match the fins i already have and increased thickness, because they seemed a little thin.

The mini-fins were designed in blender based on an image i found online.

Same for the knubster center fin.

The side fins can be used right after printing without any post-processing.

For the center fins the model needs to be printed two times with the second version mirrored. The two halves need to be glued together after printing.

The model has 3 small holes - use 2mm long pieces of filament to align the two halves while gluing them together using super glue.

I printed and tested all fins.

Edit 2020-08-22: Added a shorter version of the fins

Edit 2020-09-06: Added mini fins

Edit 2020-10-25: Added knubster center fins

Edit 2021-08-08: Added mini center fins

Edit 2021-12-25: Updated fcs2 and futures tabs

Edit 2022-09-25: Added new river surfing fin model for weaker waves

Edit 2023-07-16: Added v2 of the river surfing fin model and a center fin model for the bigger fin

Edit 2025-02-07: Added futures fins with deep tab and 6 degree angle. The models without built-in support require support in the slicer.
Note: I haven't printed the ones with built-in support yet. If you do please let me know how they turned out or improvements are required
