I added a cable organiser at the back to loop the extra cable around. The Ant Lion Kimura cable is long and would otherwise touch the floor. The distance between the circles have been sized for the Ant Lion Kimura cable, but you can use the custom file to fit your IEM cable perfectly.
If you want to adjust the size of the circles that hold the IEMs in place, download the custom one and load it into tinkercad. The dimensions of the end circles are 20x4x20.
The author remixed this model.
This can be mounted using some screws underneath a desk.
