acoustic panel Flexible mounting with M3 insert

I used the radius idea as an idea for my acoustic panel coat rack. So i made one with my own dimensions, so credits for the initial idea. With this at the base I rebuild my own hook version so it does not use any screw fixation to the wall. This model is suitable for acoustic wall panels with a 13mm space in between with the model i used an M3 insert which can be bougth anywhere.The one below is an example that can be used.I used my fingers to rotate it to the fixed position and after this I used my new designed hooks to fix them together with a black countersunk screwI do have to say that this is my starting model when buying a 3d printer but I love the final outcome in my home. The final result looks like this: (I will update the additional hooks seperately)
