Cradle for Mini APM Pro

In one of my aircrafts I have to detatch the APM to plug or unplug any of the peripherials. The usual solution could be i.e. velcro fix the APM, but I was afraid that this would influence the board alignment.
Therefore I designed this cradle. It can be attached to the aircraft permanently and holds the APM precisely in a defined reference positon. The APM is fixed in the cradle with a cable tie.
