A Game Boy cartridge is a circuit board in a plastic shell. This is just the shell, made for FDM printers, the common home kind that melts plastic filament and lays it down in lines, one layer at a time. My other shell, the Dingus Game Kart, has walls too thin for that. This one prints on the machine you own: two halves, without the ridges or the recessed label well. It’s pretty plain looking, but that’s what you give up to get a shell off a filament printer.
Useful if you’ve got a bare flash cart board (a cart you can rewrite with whatever game you want) or a bootleg with a cracked shell, and don’t want to sacrifice a donor cart, meaning a real game you’d gut for its shell. It closes with one 3.8 mm Gamebit screw, the security screw Nintendo used so you’d need a special bit, or anything of equivalent size.
Keep the layers fine
- The settings I saved with it on MakerWorld (a model-sharing site): 0.08 mm layers, 2 walls, 15% infill, about 43 minutes
- Keep the fine layer height. The fit depends on it
- PLA is fine here. It’s not going anywhere hot
