Xiaomi Redmi Note 9 Pro / S case

This case is for the Xiaomi Redmi Note 9S and 9 Pro, but not for the Redmi Note 9 (it's a bit wider). Some of the models are designed for rigid materials and others for flexible ones. The models materials are not interchangeable, so pay attention to the file names. If you have any request on the design just ask me.
For other phone cases check this.
Here is the explanation of the files names:

Flex: made for elastic filaments like TPU. Requires support for the buttons and charger holes. Not tested.

Rigid: made for rigid (non-elastic) filaments like PLA, ABS, HIPS, etc. The entire model is a little bigger and the holes for the buttons are opened on the front side. Tested only on PLA.
Banded: It has regular horizontal grooves in the bed surface, to make the finished texture more regular, avoiding irregularities on that part, and bringing it a better grip.
Rugged: Reinforced version, with lateral grip.
