Yet another ukulele wall hanger. Tried to make it reasonably stout since the (very small) weight is bending the hooks in the weakest direction. I tried to snap it by hand but couldn't so should be fine for a soprano/tenor ukulele. Would not try to hang anything heavier though.

I suggest making the straight parts a bit longer if the body of your ukuleles is deeper than mine. F360 file included, should just be able to edit the length of that extrusion and the rest will Just Work.
