This is a case for LaBoite-Maker
An connected clock able to display some informations (see https://www.lenuage.io (french) )
The original design is available here https://github.com/laboiteproject/laboite-maker/wiki
It is good but some details was not to my taste (the open back, the lack of clips to hold the led pannels, etc…) so I redesigned almost everything on the inside while keeping the outside as is'ish
It was also for me an exercice to learn FreeCAD so it's certainly not perfect
The author remixed this model.
