Smartphone stand #4 (Z-shaped)

I made a V-shaped smartphone stand before, but there was a slight problem, so I made a new Z-shaped one.

Since I added a lock mechanism, the stand does not open accidentally when you carry it as a key chain.

I made the length a little longer. 65mm-->75mm.
And also I narrowed the slot a little.
Sorry, this has not been print tested. The photos are still the old version.
