OpenIPC Radxa Zero 3W HDMI ground station

Self-locking (no screws needed to close it).
WiFi module USB connector is hidden inside the box (no dangling wires), but requires modified (5.1k resistor) "MX-12" 90° USB-C connector.

Radxa and cooler are screwed with M2 bolts (5mm for Radxa).
WiFi module and BEC glued with hot glue.
In my case DC barrel plug was also glued, but depends on your model.
