Thank you very much @Jejelinge_724355 for your hard work and sharing. I look forward to getting into one of these other projects. It is thanks to people like him that I have been able to learn new things.
On the main case I accidentally broke one of the clips of the ESP32, so I modified the case and added a support that is glued with double-sided tape.
The bottom of my case did not hold properly, I added 2 pieces that are also glued to the double side and allow you to fix the bottom of the case with 4 screws.
I added on the bottom of the box a toggle button, a power connector and a led.
You could see the ESP32 from the outside, so I added a piece to hide it.
