Crossfire 2 KK2 vibration dampering adapter

Crossfire 2 is designed to be optimized for the APM controller by mounting to the frame via vibration dampening bushings. So i create this adapter to fit a dampering for the KK2 board and other boards with 45mm between mounting holes.

Printed with PLA at 20% infill without supports.
