Thinner case for TM1638 LED&Key and microcontroller

This project is for the [TM1638](https://www.amazon.com/dp/B093SQLCLK).

The ESPHome code for this project is [located in a gist](https://gist.github.com/kdorff/396a11b5bb29142f09c1f52242c546e5).

**WARNING** TM1638 boards are not all the same. At the time of this posting, this case fits the TM1638 listing **mentioned above** but didn't fit another listing I ordered.

I still like my previous remix of the TM1638 - this thinner version doesn't necessarily accommodate the ElectroCookie PCB or pin headers, but if you are willing to solder the microcontroller directly to the TM1638 (using solid-core wires), this is a more svelte case.

I assume you are using a micro-usb cable to power the microcontroller. Power comes in from the bottom. Need another side? Let me know.

The case uses countersunk [m3 screws](https://www.amazon.com/gp/product/B07CYNKLT2) to affix the lid to the case, instead of glue or tape. Lid and Base to attach using four m3 screws (12mm is about perfect).
