3DS / DS Cartridge Holder

A simple cartridge holder for 3DS / DS cartridges. It strikes a good balance between keeping the cover art on the cartridge visible, but also having enough supports to keep the cartridge from falling out if the holder gets bumped or jostled. I only designed it two slots wide because my printer has a small print bed and this is as large as I could go. If people are interested in a larger version, let me know in the comments and I could be convinced to make another version. Enjoy.
