3DS and DS carts to put your Switch carts into ⊟
This seems to be a) a way to store your Switch games in the same cases you store your 3DS and DS games in, b) a thing people wanted to do because they had 3D printers.
If you find yourself in either situation, you can download files for a DS or 3DS cartridge-shaped case.
