Im the one who made the cases for gman, pengy, and myself. It currently holds the record for the smallest Wii portable. Designing and assembling a case where everything is so tightly packed is pretty miserable, even for seasoned veterans. I would not advise trying for such a small case for your first portable. Start with something bigger, like a Wii U gamepad case or a ZN40, as they will give you room to breathe. Then, once you get the hang of things, work your way towards smaller cases.
