I was looking since a long time for a good solution to keep my earbuds well organised.
But none of the one I found did the job.
But one of them was almost what I was looking for:
the cable tie from Rainers (https://www.thingiverse.com/thing:3961115).
So I use this as starting point to create a new one.

I hope you will enjoy it as I am.

Also it is a very quick print: 9minutes!.
