[Reflect on the process of making this project. What did you learn? What would you do differently?]

First of all I would like to thank Lillian for brainstorming with me! 

During the modelling process, I realized that I forgot to take the thickness of the outer box into consideration, so I had to re-calculate some of the dimensions. If I were to do it again, I would definitely make sure the dimensions are correct before modelling. And I would send my project to 3D printer as soon as possible.

I also found a problem with the small compartment. As shown below, it is almost impossible to get the small part out of the box if it stucks in the corner. I would also have to come up with a solution to this problem.
