SUP iSUP Paddleboard river fin for US BOX

A short version of the paddleboard fin ideal for shallow river use. The recommended material is PETG, it is possible to print from the attached .stl vertically or diagonally, but for the greatest strength I recommend printing in two halves and from the attached 3mf files and after printing, glue with CA glue together. Lightly sand the glued surfaces with sandpaper before gluing. The fin is very durable and, thanks to its profile and slimness, it´s also damn fast. ;) Added a new version of files
