Pc Headphone holder

I modeled here three different headphone holders wich can be mounted on the left/right side of an monitor. The v.1 version fits on thicker monitors, while the v.2 and v.2.1 are for smaller once. The v.2.1 has also usb slots to store Usb sticks. You can mount the headphone holders with doublesided tape or like me with hook-and-loop tape.
