Universal Bottom Cover & Hinges for Cardputer ADV

This is the universal bottom cover for my Cardputer ADV external display mods.

The design includes integrated hinges and works with both of my display versions:
- 2.4” display version
- 2.8” XL display version

Instead of modifying the original Cardputer case, this part fully replaces the bottom cover while keeping the mod reversible and clean.

The hinge mechanism is built directly into the model, allowing the display assembly to open like a Nintendo DS.

## Features
