Hello!
I started the CORE Modelling path last week and as a kind of consistency challenge I plan to upload my results here. I hope it keeps me motivated (I'm that kind of person who needs it a lot, I've lost count of the times I picked up and abandoned Blender) by showing some progress.
Also, constructive feedback is highly appreciated.

And the sci-fi crate:
I added a few insets as a further exercise and corrected an ngon that somehow showed up on the crate's side.
