Wemos D1 Mini with OLED case and stand
I used NTP time. Put your SSID and WiFi password in the file.
I built the case and plugged in the USB cable and discovered the display was upside down. I spent some time trying to flip the display but gave up after an afternoon. I designed and built the first WemosClockBase.stl. Then I discover the USB cable was to stiff. That is when I designed and built WemosClockBase-a.stl.
Good luck and enjoy.
