First print: Broke after a few months on the wall. I recommend extra perimeters and possibly gyroid infill. I had it over my dogs bed. Thankfully the weren’t in it when my snowboard fell. Second print: I printed in PLA with 0.2mm layer height and 30 perimiters (effectively solid). We will see if this is stronger. I also took a closer look at the design and have some recommendations (I have a mechanical engineering degree, but it's not my day job). 1) I think the main problem is that the board ends up sitting in such a way that it applies a large force at the top front of the hook (see photo). I think this can be fixed by changing the geometry. It looks like the floor slopes slightly towards the back, counterintuitively this encourages the board to rotate forwards. Sloping the floor in the other direction will encourage the bottom of the board to make contact at the bottom of the hook where it's stronger. This way the wall also makes contact and supports some of the rotational force. 2) The hook has super beefy dimensions, but the chamfer on the inside makes the part effectively less wide, therefore less strong. I think if you fix #1 then this won't be a problem, but it's worth pointing out. It might look less cool, but removing this chamfer (see photo) will make the part stronger in the dimension of failure.
