Made a lens mount for the Gameboy Camera. 3D printing is great and all, but I have dozens of these Kinder Surprise egg capsules in a box collesting dust, so why not use that instead. The rubber band makes it fot snuggly and leaves you some adjustability. The lenses are from a phone kit, including Macro, Wide and Fish Eye lenses. Now I just need a Telelens to make it complete.
