After my previous upload, I redesigned the case from the ground up.
What's changed:
+ The wall thickness is uniformly 1.2 mm everywhere.
+ I deleted the bridging above the buttons, corners became rounded.
- The case is thicker, not “so graceful”.
It is necessary to use a support, due to the overstretching of the second and third layer of the wall (due to the rounding of the phone).
