The file '5 Inch Race Fin / Turle 3D Printer Model' is (stl) file type, size is 106.2KB.
2023 is a remix of a fin that had square arm tips (made round so they do not stick out of the plate) - This one is bit thicker and printed with medium TPU works great.
Also, OG Fin made years back by ErikD that can work with much stiffer TPU.
