12h led clock matrix style

My first full 3D printable led clock case. I am still working on it, just wanted to share the idea, since I discovered alot of things and ideas made by other users.
I am still test printing it to verify if everything prints fine and fits together.

The back plane (top) will contain the led strips (60 leds/m), 5 rows with 6 leds each, and each cell will be lighted up according to the time to display.

The hardware, in my case a ESP8266, will stay outside the case to have the clock more modular since it can then be controlled by different kinds of ESP8266 modules or Arduinos.

My proof of concept. :-)
Printed a first version to verify printing quality and led control. The green filament is not the best for coloring the time to display, using just white for this version. My daugther loves green!
The case does not snap together as expected, due to the solder points (I am not really good on soldering), need to adapt the required space at the outter border where
