Nodemcu Oled Box

Greetings first of all, I made this project for boxes that are not the way I want. In this project, 1 18650 fits comfortably. There are 3 mini buttons and 0.96 oled with on off switch. With the mini voltmeter, you can constantly see the status of the battery and thanks to the air holes, you will not encounter wifi blocking and you can charge it regularly with tp4056. In short, I thought the whole thing completely. I applied it, it works, I'm using it. The only thing missing was the top cover was tight, the closing places were tight, and now they are loose. I solved it with glue. All other parts fit perfectly in their slots.
