This is a video about another 3D printed 7 Segment Digital Clock I've made. This time you don't need a separate App because the application runs on a ESP8266. The size is approximately 50cm by 18cm. You can find all the necessary files on my GitHub page:

I've used FreeCAD to design the 3D model. All STL files can also be found on my GitHub page in case you want to make one for yourself.
