Hook for Acoustic Panel (no drill)

Hey Folks!I am happy to share with you yet a new version of my acoustic panel hooks. This one does not fold like my first design but instead can be inserted and easily fixed in please by rotating the hook 90°. Thereby the disk rotates behind the wooden slats. This version is again dimensioned for the version of acoustic panels which we have here at home, which has a spacing of around 18mm between the slats.Enjoy printing, assembling and using it.Cheers Update:The design is based on a friction fit. The friction fit allows the parts to connect by pressing them together with moderate force without the use of glue or screws. However, a friction fit requires small tolerance. By the use of different filament brands, a different printer or other settings, it can happen that the negative cube of the hook and the positive cube of the disk don't friction fit any more. In case it is too tight, you can simply scale down the size of the disk slightly. Is the fit too loose, scale up the size of
