Universal Headset Holder for Monitor

I created this holder for the reason that I had headphones lying all over the place in my office. Other similar models didn't fit the size of my headphones so I decided to create my own model. It is simple, effective, and fits most monitors and headphones. From the other side, you just put double-sided tape (e.g. 3M, ….).

I've printed it with PETG but PLA is fine too.
