Wall mount / Spacer for Thomann t.akustik PET Wall Absorber

I bought some acoustic treatment from Thomann.

these panels work better if spaced from the wall, so i made these simple spacers 

Just fix the main part with a scew (glue can be enough for the small panels I think) and add a nail in the smallest hole on the front

Then glue two of the bottom part on the panels (Silicon caulk works great)

I added a small piece of adhesive foam on mine so it doesn't scratch my wallpaper

Works withe the 60*60 Panel, and should also be fine with the 120*60
