Wifi cover + GPIO case for Mk4s, Mk3.5, Mk3.9s, etc.

This puts the GPIO card under the wifi card, so the pins are low and at the back of the machine and easily accessible. The GPIO cable passes through the slot for the bed cables. 

MMU text included for Wifi and GPIO symbol.

Uses 4 m3x10 (or thereabouts) screws to hold the GPIO board and GPIO board cover in place. You'll also need a 90º adaptor for a camera shutter connection.
