I saw that there wasn't one created for the MHQ2 yet so I made a simple one.
This just slides onto the stock 5mmx35mm standoffs, protecting your FC from wind and dirt.
I might create another one with the usb port exposed.
Also, I've uploaded my slim GoPro Hero HD case here:
PLA or PET recommended. ABS is usable but warps.
Print 2 vertically with .2mm resolution so that the standoffs just slide right into the holes. Mirror the other one. Having a brim helps to keep it upright.
