GBA Extended Battery Cover
thingiverse
Per the request of HoraceAndTheSpider over at the Freeplaytech forums, I created a custom battery cover for the Gameboy Advance to replace the standard issue cover. The new cover accommodates larger or thicker batteries that can power the FreeplayZero/CM3. The Battery Cover was designed from scratch in Fusion 360, drawing inspiration from roijeric's GBA Replacement Battery Cover. A significant amount of reworking was required to refine the clip design so it would print correctly and securely snap into place within the GBA case. The end result is a snug fit that holds everything together nicely. The Fusion 360 archive can be downloaded here. Feel free to remix the design to suit your specific battery needs.
