1. Are there any features you saw in the google home mini teardowns that you might consider adding to your enclosure design?
Explain what feature you will add and why.
I didn't see anything I'd like to add, but I enjoyed learning about the intentional design choices made when using screws. Screw placement can be asymmetric or misaligned to make the assembly process easier by directing the exact way to fit components together. Ribs are also a great choice to include around screw bosses, and when you don't want any conductivity between components, metal screws are not the best option.
2. Create another branch of your CAD file
Update your CAD with features you saw in the teardown if you so choose. Otherwise, continue making the necessary changes your designs require.
