Acoustic Panel Foldable Hook (no drill)

I designed this foldable hook for my acoustic panels so I don't need to drill in the panel nor the wall. This version fits perfectly on my acoustic panels which have a distance of about 18 mm between each slat. By rotating the two knobs, the clamping disks interlock behind the slats. This creates additional friction to the four outer leaf springs, especially when there is weight attached to the hook. Leaf a comment what you think about this design and if I should prepare versions for narrower or wider slat distributions. Dis design uses an M2 16 mm countersunk machine screw, but you can alternatively use a small piece of filament as you can see in the picture.
