ESP-01(S) Single Relay Module Box

I had an ESP-01 Relay module dangling from wires in my utility closet for years, used for my doorbell chime (https://frenck.dev/diy-smart-doorbell-for-just-2-dollar/), I figured it was finally time to properly mount it. This is my solution. The back has 2 holes for screwing it into the back wall and one spot for adding an M3 heat set insert (because I had a few of those lying around) so you can easily secure the module in the case.
