Prusa Balance Game Box - thinner walls (less material needed)

Prusa Balance Game is great and the Prusa Balance Game Box is a great way to pack it. However, the Prusa Balance Game Box requires quite a lot of material. I have slightly adjusted the model by making the walls of the box thinner near the bottom; it works without any issues and saves around 15g of filament (15% infill). The stand and connector are the same as in the original model. I printed the box with PLA, but all the materials should work fine.
