About this 3D model

Newer version: http://www.thingiverse.com/thing:366413 Inspired by rcexplorer.se I created my own version of a Tricopter Yaw mechanism.Printed with Colorfabb XT and 50% infill to be on the safe side.Parts you need:9x4x4mm bearing, 4mm rod, Bluebird A206 Servo, and a motor with a 25mm ( diagonal ) hole spacing. Enjoy.Video of it in action: https://www.youtube.com/watch?v=yixt5YQAoiI
