Tracer Powerbank Case

I bought this tracer powerbank two yrs ago. I was carrying it in original foil so far not to scratch it inside bags or backpacks. You know probably that it has this rubber-like surface that is super scratch sensitive. Finally my foil just broke so I decided to fully make outer case for it. Surprisingly, it fits perfectly so it does not require gluing or taping. This is one of my first project so you could observe some mistakes in files.
