TKey-G1: Keyboard dock / Kickstand for Toughpad FZ-G1

This is a stand + keyboard base I designed for the Panasonic Toughpad FZ-G1.It can be easily assembled and disassembled using two M4 screws. It's compatible with a thick battery. You can also use it as a desktop stand without installing the keyboard.

(Due to the G1's heavy body and the lightweight keyboard, the final installed form resembles a Surface.)
