Remixed from Parametric Gimbal, prints already assembled http://www.thingiverse.com/thing:100362 by Bluebie.
Printed on Ultimaker 2 w/ 1.75mm ColorFabb filament. Center ring shrank too much when using a 0.4mm shell thickness . Switched to 0.8mm shell thickness and model printed fine. May require some adjustment to get a smooth spin.
