This case is for the phone Samsung Galaxy J7 2016 version, that is j710 models; do not confuse with the J7 Prime, g610 models. 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.
Update: Since this was one of the first phone cases I've designed, it has some flaws I learned over the years. Every model updated after November 17th 2021 is based on the new design, more accurate and, to me, easier to modify.
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.
Por el día de la independencia argentina, el 9 de Julio, voy a actualizar algunas de las carcasas para celulares con una versión que haga alusión a la bandera argentina. Por la finura de algunas partes, este diseño sólo es posible en celulares relativamente grandes.
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. Not tested for the models updated after Nov 17th 2021, the rest tested on TPU.
Rigid: made for rigid (non-elastic) filaments like PLA, ABS, HIPS, etc. The holes for the buttons are opened on the front side. Tested only on PLA. Tested on PLA for the models updated after Nov 17th 2021, the rest 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 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:
