After years of using another desk headphone holder I have started to get passionate about minimalism and consequently I am trying to have the clearest desk possible.
My headphones are wireless and have the ability to attach a small microphone through a 3.5mm jack.
There are many wall and under-desk headphone holders but none of these had a compartment for the microphone and for a possible charging cable.

This is why I created this headphone holder, very sturdy and very thick because this way I can throw my headphones without looking if I position them precisely.
On the sides there are two small clips suitable for cables and microphones with a block so that they do not fall out at the first accidental blow.

I personally printed it with 20% infill and in the upright position without supports.
Being so robust it does not create problems even if printed in a vertical position (also because it has to support a reduced weight of the headphones), but if you plan to place heavier devices I recommend you print it in a horizontal position with the help of supports, so the layers they will be much more resistant.
