Stand-Up-Paddle Fin

I decided to create a shorter fin for my SUP (Stand-Up-Paddle), so i can also paddle in shallow waters.
It works for my SUP F2 Sector 10,5", but certainly also for other models.

I printed the parts with the following settings:
Top/Bottom solid layers: 1mm
Perimeters: 2
Infill: 15% Gyroid
Resolution: 0,25mm
Material: PLA
Supports: No
Brim: No
Nozzle: 0,4mm
