It's a Earplug Cabledrum to store the cable efficiently. The object is inspirated by the "earplug Cable Tidy" of muzz64 and can be seen as an emproved version of it. Here is a link to his model:

My object can be printed without support, the maximum overhang is 30°.
The v-shaped holes in the base plate enable the secure attachment of a lot of different earplugs. Radii on each edge touching the cable to prevent cable breach. The little "tower" in the middle is used to attach the headphone jack to it (3,5mm). How to use it can be seen in the pictures ;) (Printed in standard PLA)

I hope you like it :)
