Could you please send me the stl files you made and take plenty of photos of how it fits? You have pretty much confirmed a fear that I had about this project. I was basing my designs off the gameboy cad/stl files I got from HERE, and I was worried that there would be more differences besides the place for the face buttons. I would like to update my gameboy case template.
Also I realized something, since I have a see through case it makes it a ton easier to pick out the right spot for these should buttons. These brackets can also be used for drill guides.
