The original was created in purple PLA.
A scan of the sketched-out design.
I wanted to emulate both my brother's and Zeurel's drawing styles to truly personalize it for my brother. My brother appreciates geometric designs with scratchy and straight lines, and his self-described style is "purposefully ugly." Therefore, I decided not to round any of the corners or curves on the box to give it the same "sharp" feeling that his art carries. I extended his original linework to cover most of the box so that the design wouldn't feel isolated to just the top of the case.
Additionally, the box was supposed to carry the maximum number of games while retaining relative symmetry and a similar size to the Mario Question Block. I tried out a few different configurations with the cartridges themselves before settling on a capacity of seven cartridges, an addition of thickened walls to create a square base, and spacing between cartridges for fingers to be able to fit in.
For the lid's connection to the box, I decided on circular rails to produce a smooth sliding motion as the games are unveiled in their compartments. Transportation was not one of my requirements as his games don't usually travel with him and instead remain on display on his shelves, so a clasp was not included to keep the lid in place.
