3D Model
STEP is the industry standard format for 3D files. You can open it using the free CAD (Computer Assisted Design) software Design Spark, or any other CAD software like SolidWorks, Catia, etc. Google Sketch is free but only the paid version can open STEP files.
Case
If you want to build your own case, wether it is by laser cutting acrylic, 3D printing ABS, machining stainless steel or carving wood, you can use the following template. Make sure to select a scale of 100% when you print it.
Bootloader
The bootloader is a small program that permanently resides in Gamebuino memory which allows you to load games via SD card or USB port. Under normal circumstances loading a new game into Gamebuino would require you to use an external programmer connected to the Gamebuino's ICSP port. The bootloader makes this process easier and faster by eliminating the need for a separate hardware programmer.
