Stardust V3 Chassis with micro-USB and 2.1mm RC port

This particular version of the chassis I created to support the dual charging scheme unique to the Stardust V3 design:
- charging via USB (micro-USB port) in the upper section
- charging via conventional 2.1mm recharge port in the mid section

The upper part can hold a 28mm speaker (or smaller). The lower part of the chassis houses the Li-Ion battery (dimensioned for a 18650 type) and the Stardust V3.
