1c:T7a3,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.
This is part of an update for the 2020 Valentine's Day, in which I add for most of my phone cases a "heart" version; a model with a hole in the back side with the shape of a heart.
2021 is the year when most of country started the covid-19 vaccination; that's why I added a design with the 2021 with the "0" as a virus silhouette and the "1" as a syringe.
For other phone cases check this.
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.
Banded: (h horizontal, c concentric) 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.

I spend part of my time making these models, letting them available and free for everyone. If you want to support my work, you can contribute with me here:
