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 screw

I 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)
