CC3D 45mm plate mount adapter for drones

This is a 45mm plate mount adapter for CC3D flight controller in an original transparent case. It comes in two versions: with and without brackets to better attach the CC3D. Between the adapter and the case there is a small space to insert thin foam to limit vibrations. The adapter also has additional holes for the extended version of CC3D with USB HID, USB VCP and SWD ports. The adapter is mounted on the drone plate with M3 screws and nuts.
