Anbernic RG Cube XX Battery Upgrade Shell

A 3D printable rear shell for the Anbernic RG Cube XX which allows up to four 18650 battery cells, for an effective 4x increase in battery life (I got 18 hours in performance mode).

The shell maintains the same footprint and dimensions as the original device, only removing the valley between the grips to make room for the batteries.

Print flat on bed with no supports.

Use tabbed cells and batteries need to be soldered in parallel. Balance battery charge before installation.
