Fix for newer versions

Fix for newer xiaomi m365 version. I have m365 1s and it works like a charm.

-changed the "nut-holder" shape to fit inside the rod
-even less height (0.2mm - 1 layer)

It will be very tight, but I hope it will shape itself in.
Still clicks without rising the lock grip, but barely.
At first it may not click in, but I took it for a short ride and it works ok.
