Tangle free earbud holder

This is an earbud holder designed to hide the cord away to protect it while it is being carried in a pocket or bag. To use this, put the earbuds in the holes with the cable coming out the hole in the outside ring, then turn the inner piece to wind the cord inside the body of the holder.

This design is very effective. It is not completely finished. There are a few parts I would like to improve but it works well enough that I haven't felt the need to finish it. I thought I should post it anyway
