Headphone Holder (Double side taped)- Headset

This is a 2 Parts headphone holder, intended to be taped into the wall (double sided tape).

The screw in the middle (M4 40mm with a nut on the other end) serves the function to transfer the strain towards the base of the part. Not sure if it is necessary.

I'm uploading the 123D File with sketches if one wants to remove the hole (screw) or make adaptations.
