This case is for the phone Xiaomi Redmi Note 8 Pro, which model number starts with "m1906g7", it will not work with Redmi Note 8 T or the regular Redmi Note 8. For the later I made this case. Thanks to Grzegorz Juszczyk who helped me to finish this model testing the previous model.
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.
Models that don't have the tags "_aired" or "_rugged" in the file's name, have their back thinner, so the camera is unprotected of hits in that part. Here is the explanation of the files names:

Flex: made for elastic filaments like TPU. Tested on TPU.
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.
Aired: It is widely opened in the back so that the phone can dissipate the heat easily.
Rugged: Reinforced version.
Banded: It has regular horizontal grooves in the bed surface, to make the finished texture more regular, avoiding irregularities on that part, and with a better grip.
