Horizontal Monster Mouth headphone holder

A horizontal version of the [famous Monster Mouth headphone holder](https://www.thingiverse.com/thing:1657541) but changed to be made horizontal so it can pinch on desks that have vertical walls on the side (see images).

It accommodates desks up to 25.83mm thick by default and you can scale it. It is 90mm long (screw excluded).

Check the printing notes for details.
