quatric/printmiiout

PrintMiiOut takes a Nintendo Mii, the small custom avatar characters used on Nintendo consoles, and converts it into a 3D model file that can be sent to a 3D printer. To get your Mii into the tool, you can enter a Nintendo Network ID or Pretendo Network ID, upload a binary Mii file directly, or upload a QR code image that contains Mii data. Once a Mii is loaded, the tool runs it through a processing pipeline built on Blender, the free 3D creation software. This step attaches the character's mesh to an internal bone structure and applies smoothing so the resulting shape is suitable for physical 3D printing rather than just screen display. The end result is exported as an STL file, the standard format most 3D printers and slicing software expect. The project itself is presented through a simple web interface built with the Flask web framework and plain CSS styling, so no separate desktop app is needed to use it. The README is brief and does not go into detail about installation steps, hosting requirements, or configuration options. It does credit two other projects it depends on: Blender for the 3D processing work, and a separate Mii rendering service run by a third party developer that supplies the actual character data used as the starting point for the model. Because the tool relies on Nintendo account identifiers and an external Mii rendering service to fetch character data, using it depends on that external service remaining available.
