This is an anti-vibration mount for multirotor control boards such as the KK Multicopter, Hobbyking boards or Cirus Multiwii. It should fit any square board with 45mm mounting hole spacing.
Note: I've not yet received my first order for this, so it hasn't been tested yet. I've decided to post it for purchase due to Shapeways only offering this material for certain through June 20th. Order and use at your own risk.
