Clock frame

I had an old cheap chinese digital clock on a pencil holder that I did not like. But I like that clock.
It just fits well on my workbench, that has some cups that I use to keep some tools. All identical, to follow some organization standard, including one that I use just as a pencil holder.
So I decided to model a frame for that in Blender and print it on my brand new Flashforge AD5X, in PLA, in a way I can attach it to that pencil holder.

And... Here it is! Worked like a charm from the first try!
