This is just a basic wall mount for headphones. I attached it with double sided tape, but you could use command strips if you were worried about damaging the wall or easily add some holes if you wanted to use screws. 

If you insert a properly timed filament change you can get a different colored headphones icon in the middle. At .20mm layer height, I switched to orange from layer 3.0 to 3.4 mm in order to get this color added in. I printed this in under an hour on my Prusa Mini with 15% gyroid infill and it seems plenty strong. 

Enjoy!
