I've designed this piece to mimic the screw hole positioning on the top plate of the crossfire 2 so that it can act as an anti vibration clean plate with the use of anti-vibration bobbins or home made silicon tubing. Bobbins: http://www.getfpv.com/m3-anti-vibration-sandwich-mount-set-of-6.html DIY Silicon Tube Vibration Mount: http://flitetest.com/articles/vibration-reduction-camera-mount-v2 Printed in PLA with 40% infill. Made in Sketch-up then exported to STL and printed with slic3r and pronterface.
