This is a modeling for my sennheiser IE 80s earphone.

The original design of  the cable collecting case is formed by high quality paper and users have to manually round up the cable by aligning by the side of the outer case before it can be put into the case

​

For my improving version, it allows users to round the cable much faster than the previous way by simply plug-in the earphones into the hole then turning the inner part from the top of it.
