Macbook pro case with book holder

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/07lZ3ZlOZ0d
I have created a MacBook Pro plastic case with a book and paper holder at the back. I am a person who likes to carry minimum stuff in the bag. I always wanted something attached to my laptop so that i can carry my notebook, papers and a credit/debit cards. By using this case, i do not need to carry books, pen, wallet separately i can put all these in the silver folder that is attached to the case of my laptop and stay organized at all times.
