SUP Paddleboard Fin for use on the standard paddleboard fin slot (common on amazon/walmart boards). My ROC board's fin broke the second time out. I remodeled the makerworld model above into a thicker version (maxes out the base thickness in the slot) to make it a bit sturdier. Fin is ~216mm (or 8.5in) tall
Also lends itself well to making it out of TPU, to make it indestructible. But you can try any material you like.
I recommend 100% infill as it is a functional part after all… It is roughly 400g of filament. But perhaps you could get away with 50% or even 40% gyroid infill in the upper sections. If you want to gamble on half the filament usage, maybe you'd win :)
I tried doing it in TPU at first, but found it was expanding a bit more than I'd like for tolerance. The foot barely fit in the slot... I recommend a test print of a cube or the base itself to test dimensional accuracy before doing this part (takes a full day or more). I eventually scaled my part in the slicer to 99%. But in the process I made a new model that has a reduced footprint, for better fitment without scaling.
