Samsung Galaxy A02 A04e A12 F12 M02 M04 & M12 case
This case was designed for the phone Samsun Galaxy A12, but by its size, shape and button places, its compatible with the A02, A04e, A12 Nacho, F12, M02, M04 and M12 model. For the A02s, M02s, A03, A03s, and A03 Core, this case will probably work, because it's the same size but slightly different shape, so I recommend trying this case instead. 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.
2021 is the year when most countries 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:
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 buy me a coffee in Ko-fi:

Here is the explanation of the files names:
- Flex: made for elastic filaments like TPU. 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 on the A12 on PLA. The A03 was tested with this case and it fits, but this case fits better.
- 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.
