TPU. 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:

Aired: It is widely opened in the back so that the phone can dissipate the heat easily.
Rugged: Reinforced version with grip marks on its sides.
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.

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:
