Drafting Project

[Acolyte]

Hey, I have this assignment for drafting/general engineering about redesigning something to be more efficient and cost-effective. I was thinking about maybe redesigning a game controller, but I'm wondering what would make it more efficient (placement of buttons/the way it's grasped/ect.) and what materials would make it cost-effective. I was thinking just molded plastic for the body, and whatever metals are needed for the electrical stuff. Any input would be nice.
