Shokz Half Case V4

Here's V4 of my Shokz Half Case.
The following is .w.r.t my earlier designs. Much better fit for the headphone ear loops, with a simpler latch mechanism. Charging connection, with the headphone in the case, works well. The LED viewing slot is in the right position.
I'm very happy with this version.

I made this case to provide a bit of protection for my headphones which hang outside my backpack.

I use a straightened paperclip for the hinge.
