So you got a sup board or paddle board, but what when you are not using it? I store mine tied with straps to the ceiling in the garage, but those fins... they have to be removed, you don't want to walk into it. So I made a print, screw them to the wall or one of the beams of the ceiling, and you're good to go! Slide them in, and never hurt your head at them.
Made this one in OpenSCAD, so if you fin has other dimensions than the fit ocean board I use, feel free to edit them!

Mount them a bit rotated, so the fin won't slide out and water runs down, there is a small cut out so it can flow ;)

Designed for Fit Ocean Magic Glide 2020, but for sure it will fit a whole bunch of other boards!
