A spacer for increasing distance from speaker to ears.
I got to much pressure on my ears wearing these headphones. This helps to reduce it.
The fabric still touches the ears but not the speaker themself anymore.
I printed it in two parts, and then glued them together and lastly glued it will a couple of small drops of superglue to the headphones themself.
There is also a part included which are not split, that need support.
